Suggest Treatment For Cracked Heels
could be splinter/plantar wart
Detailed Answer:
Hello and thank you for your question
It could be that you have something in there that needs to be removed like a splinter or other foreign body. It is also possible that it is a plantar wart. Soaking it and filing off the dead skin with a nail file may give you a better idea. If it is a plantar wart then you should see a clear center core and possible some tiny black spots around it. In either case you are probably going to need to have a doctor look at it and possibly shave it down with a scalpel, especially if it is painful. If it is red around it (I can't really tell from the photos) then you should be seen right away since that could mean infection.
Please see a doctor about this soon
