Hello,
From the sites that you have mentioned, scabies should be ruled out. Scabies produces small red bumps and blisters and affects specific areas of the body. Scabies may involve the webs between the fingers, the wrists or other folds of body.
I feel that you should get it evaluated from a dermatologist. The fluid exuding from the blisters can be sent for examination to find out the confirmatory diagnosis.
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 doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
