Hello All! I have had what looks like to be a growth of dead/dry/thick/cracking skin on my thumb which has not healed in months. I am very bad about leaving it alone though because i am constantly picking at it. I was wondering what is the best way to get rid of this dry skin patch on my thumb knuckle. It almost looks swollen and protrudes a little off the thumb. Is there a medicated lotion i could use to treat it or would seeing a dermatologist be a necessity? Thank you!
