Hello,
Peeling and sore skin below the fingernails can be due to dermatitis skin or psoriasis skin. If it is dermatitis skin then combination cream or ointment containing an antibiotic and a steroid is quite useful.
If the symptoms persist then get an evaluation done from a dermatologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Thanks so much! I have the same problem and I could never figure out what it was! I figured it was just because I always kept my nails relatively short up until now when I'm trying to grow them a little.
Thanks again!
