I am hoping someone has experienced this before & can give me some insight to what it might be. The tip off my right thumb will get hard, numb, then peel away layers of skin (painful at times), and within weeks, regenerate all new skin, just to go through the same process again weeks later. No other digits have ever been effected. I am not diabetic, nor do I have any other chronic diseases or skin disorders. Anyone ever experience anything like this before?
