[|Human|] I have a recurring rash on my forearm that I believe started several years ago when I got into some bad poison oak.  Every so often my forearm gets one or two little blisters that really itch. If I scratch it it oozes and spreads to more of my arm.   I went to one dermatologist a couple years ago and she did not help.   She just took a biopsy and said it was not cancer but did not or was not able to tll me what I had
[|AI|]  Welcome to Chat Doctor forum Thank you for your query I understand your query regarding your skin problem. It is difficult to give idea about diagnosis only from description, It looks like edematous dermatitis or allergic dermatitis. For itching, you can use anti-histaminic tablet. You need to apply good moisturizer cream over skin. At oozing area you can apply antibiotic cream, other area mild steroid cream will work.it is better to consult other dermatologist for second opinion. I hope I answered your query.
