At me on fingers of arms or hand the skin grows coarse, turning in as though in a small callositas, and then bursts up to a blood. After a while ranka it is tightened or delayed, but then bursts again and again. Such status lasts some months. Ointments give only temporary effect - after a while all begins all over again.
Prompt, what is this the sore and how to treat?

[New settlers V.S.]

It can be allergic reaction of a skin in the form of ekzemopodobnyh displays, a mycotic affection, not a callositas, and a wart, etc. That for "sore" we shall treat and how? I Wish health.
