I have had corn problem in both my feet since Aug 2020. With salactin paint it used to reduce and reappear. Right now I am on vacation without easy access to clinics. All my other corn have completely gone while one seem to be hurting me. Pus seems to have formed but luckily it hasn't broken. Earlier a similar thing happened but it subsided on its own without any medicines. Attached is the picture. I have been walking with socks and shoes on. While i thought it was subsiding today it seems to have become a bit bigger. I don't have access to salactin paint. Have been using framycetin. What can I do? I will be back home in two weeks- can I wait until then before consulting a doctor? I don't have diabetes but family history- so I Monitor regularly. Home glucose  test taken two weeks back were well under control.
