Talk:Callus

Shortcomings
This page is useless. It doesn't explain anything about calluses. The "causes" that it lists are not causes; they are all the stimuli that trigger caluses, and they are all the same. Do we need to list every kind of human activity involving skin perssure? How about describing the physiological mechanisms of callus production? How does it work? What patterns of stimulation are more callus-forming than others? Are there dependencies on heredity? Diet? —Preceding unsigned comment added by 154.20.2.202 (talk) 01:49, 8 December 2008 (UTC)  that is all innocrect.


 * I agree, the causes section is absurd and I am going to edit it down. OngoingCivilUnrest (talk) 19:15, 9 December 2010 (UTC)

Not OOS
As one who treats these I can tell you that it is NOT OOS. It may happen that some occupations may cause some pressures; however if you expect to explain KPPH (Keratosis Plantaris et Palmaris) or Heloma miliare, or even changes secondary to non-shoe wear then OOS fails as an encapsulating category DrGnu23  August 10, 2004, 1958 EDST

I want to move Callus and Corns of the Foot to Callus, but there's a redirect at the latter; how do I get that moved? It appears someone has just now moved ITIS to Integrated Taxonomic Information System. How do they do that? grendel|khan 02:56, 2004 Aug 7 (UTC)
 * Anyone can use the Move tab if nothing exists at the target name. Admins can delete redirs in the way of a proper move without any overhead process. I'll go take a look. Niteowlneils 03:01, 7 Aug 2004 (UTC)
 * Um, based on the content in Callus and Corns of the Skin (calluses and corns seem to be mentioned pretty equally often), the name seems proper to me, altho' someone else might have a different opinion. True, the 13 articles that link to it all go thru the callus redir, but it wouldn't really take very long to fix that few links--I've tackled redir pages with hundreds of links. Callus and Corns of the Foot doesn't exist, and seems like it would be redundant. If anything, it should be a redir to the current article, whether it gets moved or not. Niteowlneils 03:14, 7 Aug 2004 (UTC)
 * Er, on second thot, the name probably is due a fix to match singular vs plural, if nothing else. Even tho' it's contrary to most WP title convention, I'd probably vote for Calluses and Corns of the Skin as I think it makes a lot more grammatical sense, but would very much like at least a second opinion, if not a third, before moving it either direction. Niteowlneils 03:14, 7 Aug 2004 (UTC)
 * Ack, case problems, too. Now I'm thinking Calluses and corns of the skin. Thots, anyone? Niteowlneils 03:14, 7 Aug 2004 (UTC)
 * OK, having digested the article contents further, and seeing nothing relevant on the talk page, I'll ask here: Is your argument that, since corns (apparently--I'm way of of my field here) are a particular type of callus, that the title is redundant? Niteowlneils 03:22, 7 Aug 2004 (UTC)
 * Corns are indeed particular types of calluses. I wanted to move the article to a more general name; who wants to link to this huge kibbly article name every time they mean 'callus'? Also, since 'corn' is already in use, the disambig note there pointing to 'callus' is perfectly appropriate. (There are also bone calluses, but they have their own article. Foot calluses are the same type as guitar players get on their hands.) So, yes, the title is redundant, as well as being too long, badly capitalized and overly specific. grendel|khan 21:36, 2004 Aug 8 (UTC)


 * DrGnu23 (primary) here.Ok .. I suppose that indeed Corns and Calluses of the Skin describes a particular area. More likely it would /should be hyperkeratoses. Corns and callus seem to be mostly on the palms and soles and as such are a 'specialized case' I'm not quite sure where all this should go at the moment .. lets just let this sleeping dog lie until the general medicine sector gets flying a bit more. I'll probably start to add the special cases (AND some lovely pictures) to all this as soon as I get a bit more handy with the picture thing.

cell callus "disambiguation from "Primary topic"
Hello. Currently callus redirects to this page, Callus and Corns of the Skin. I guess that human calluses are the primary-interest reference for the word "callus" so I didn't want to make a disambiguation page at the entry for callus. Rather, a disambiguation for cell callus has been added to this page, because callus is used very often in biology research to refer to a "Cell callus". Raazer 21:52, 22 Sep 2004 (UTC)

Image, please
This article desperately needs a picture or two. Can anyone help? --Ashenai 23:05, 20 February 2006 (UTC)


 * Man, that picture is just horrible, can't even look at it. Could it use a hiding mechanism or something?? :-) just came by to read on musician calluses! (don't play with my feet yet) --Nathanael Bar-Aur L. 04:47, 7 October 2007 (UTC)

I just tore my callus at the gym today.. About the size of a penny. Want me to upload it ? —Preceding unsigned comment added by 146.131.120.2 (talk) 19:22, 12 January 2009 (UTC)

Calluses on hands would be a lot les offensive than a foot. Let's do out best to get a less revulsive picture posted. -- ANON

Tiny point
Re: ' "Corn" used to be a generic term for grain. ' It still is in England.

Steak Knives?
"scraping the foot with a steak knife may be warranted":

is this really good advice to give out? i can see horrible injuries happening....

Causes of calluses
It was mentioned that playing video games, that involve the d-pad can cause calluses on the thumbs. Also, with newer gaming technology such as touch screen technology, you can get a callus on the finger which the stylus lies on. Also you can get a callus from knitting, where the needle rubs against the skin. Violet yoshi 00:08, 10 May 2007 (UTC)


 * I don't think this page needs anymore specific examples of how one comes to acquire a callus OngoingCivilUnrest (talk) 19:15, 9 December 2010 (UTC)
 * I think it should be mention that you could get them by playing the guitar and that must advance players use them to play for longer periods.

Infection of calluses
Calluses can lead to infection. The harmful side effects of calluses and why these harmful side effects occur has not been thoroughly discussed and may be helpful. Typically I don't see any harm in some calluses because they may prevent the skin from damage, hence I would want to know what could go wrong. —The preceding unsigned comment was added by NewDreams2 (talk • contribs) 04:32, 14 May 2007 (UTC).
 * Agreed - there needs to be some discussion of why calluses should be removed; if they're the natural reaction of skin to excess friction, aren't they a useful protective measure? The only situations I've noticed calluses being a problem are if they break and expose a more sensitive layer of skin or if their presence leads to blisters (how?).  Perhaps this page is in need of expert attention? --Keflavich 15:33, 12 June 2007 (UTC)
 * I'd always thought that it's natural for feet to become callused, and it's only because shoes were invented that they aren't usually these days. Without them how could you walk barefoot in the wild, and shoes certainly appeared later than humans! If that's the case (and it's not some other process) then the tone of the article is too negative towards calluses. Riedquat 22:44, 2 September 2007 (UTC)

I can't make sense of this
''Corns form when the pressure point against the skin traces an elliptical or semi-elliptical path. The center of which is at the point of pressure, gradually widening.''


 * That's a sentence fragment, all right. But ignoring that, the most obvious interpretation of the second bit is that the point of pressure is found at the center of the path traced by the point of pressure, and the point of pressure widens gradually. Something being found at the center of the path it traces doesn't make sense to me. Somebody straighten this out. --Ihope127 23:53, 3 June 2007 (UTC)

callous
got rid of the "or callous" thing at the beginning since it is incorrect. It is a similar word, but it is an adjective not a noun, and hence not an alternative. —Preceding unsigned comment added by 66.102.196.38 (talk) 09:44, 19 November 2007 (UTC)

Why did someone redirect that here ? it is a different word entirely Machete97 (talk) 18:59, 25 May 2008 (UTC)

"Callous" is a valid variant spelling of "callus" in British English. See http://www.askoxford.com/concise_oed/callous?view=uk. 91.105.146.74 (talk) 12:57, 19 March 2009 (UTC)

Building calluses
Someone should write a section about methods of building calluses. It's commonly claimed online (to what accuracy I have no idea) that rubbing alcohol can be used to quickly build calluses, such as if you're a guitar player, and it would be good to establish here whether or not that's true.Fuzzyblob (talk) 06:03, 3 January 2008 (UTC)


 * Seems like there are probably a lot of urban legends/old wives tales about how to build calluses. If there are some reliable sources, go for it. OngoingCivilUnrest (talk) 19:15, 9 December 2010 (UTC)

Corn???
I have a question for someone that knows because i don't. My husband has something wich i believe is a corn; he has a small callus on the bottom of his feet but, it has a hole just in the center of it. If my assumpion is correct please somebody tell me because i am getting a little bit worried about it.

 * If it's something that causes pain or is worrisome, then I recommend seeing a doctor about it. Afalbrig (talk) 07:19, 15 March 2008 (UTC)

Oh, I had no idea wikipedia had turned into a discussion forum for free medical help. I have a red spot on my arm, can anyone tell me what it is??Skiendog (talk) 07:31, 13 April 2010 (UTC)

The whole corns section is unencyclopedic as all hell and it's fucking bullshit
It is completely inaccessible to the average layperson 74.250.177.95 (talk) 08:34, 1 January 2011 (UTC)

Good job, pedians
Once again Wikipedia puts the most extreme and disgusting picture they can right there at the top. No matter what the condition, there's never an average case pictured on the page, it's just the most horrid things you people can find. Do you people take pleasure in finding gross-out images, or what? --Buddy13 (talk) 06:08, 26 January 2012 (UTC)

Benefits
The article talks solely about possible complications, treatment, yada yada, but is it not true that callus forms as a layer of protection? As far as I know, it's not just a "bug" in the human body, but something that remains in our DNA because it was - at large - beneficial to humans (and still is beneficial in a lot of cases). If it was all that harmful, the body would probably have found a way to get rid of it by now, wouldn't it? Even if I'm spouting bullshit right now and it's not beneficial in any way, the article should mention that (backed up, of course, by sources), since it's very intuitive to see it as such. --88.76.21.240 (talk) 14:01, 7 September 2012 (UTC)


 * The protective benefit to players of some steel-stringed instruments, notably the acoustic guitar (not nylon-strung) is contradicted by the disadvantage to the classical violinist who strives to use a lighter touch with the fleshy part of the finger tip. Is there a decent reference in the violin world? It seems to be widely accepted that you cannot actually play a steel-stringed acoustic guitar for more than a few minutes without first developing some hard skin to protect the nerves from experiencing the intense pain. Initially, deep blisters form and then repeated friction slowly builds the hard layer. As long as the player maintains a frequent regime, there then follows a cycle of abrasion and replenishment, presumably from beneath the skin, otherwise the callus would be worn away in a few days. Soaking the skin can quickly break down the underlying structures and the callus will then detach. This can be a serious problem for professional players who will take whatever steps they can to prevent this happening. (See Julian Lloyd Webber's "Travels with my Cello".) --Ophir (talk) 11:05, 20 September 2014 (UTC)


 * That is super interesting, Ophir, and you have a source! A section about musicians who play stringed instruments would be rad.--nhinchey (talk) 00:02, 27 July 2019 (UTC)


 * I strongly agree with 88.76.21.240. This article only addresses it as a medical problem, and that leaves a lot of unanswered questions. --nhinchey (talk) 00:02, 27 July 2019 (UTC)

biology and evolution
This article doesn't discuss the evolutionary aspects or the cell biology. Calluses are harder than other skin: why is that? The formation of calluses is practical, since it provides protection against pain. Is it known in other species? There are a lot of scientific basics missing from this encyclopedia article.

I want to add to this page. Does anyone disagree? And if you agree, do you think "evolution and biology" is the correct description? --nhinchey (talk) 23:54, 26 July 2019 (UTC)


 * Ok, I'm doing it now. Please remove it if you feel it should be removed. nhinchey (talk) 14:53, 30 July 2019 (UTC)

Image caption incorrect
Shouldn't the picture of the foot sole calluses be labelled as, 'medial on left foot'?

, with "lateral", it suggests the callus would be on the other side, i.e. the "outside" edge of the sole, and so is confusing. "Medial" is towards the inner, or "inside" edge in anatomical descriptions.

If others concur, please amend; I don't think I can edit an image caption myself.--122.105.187.37 (talk) 13:36, 10 September 2020 (UTC)
