Blistering rash on my elbow
I noticed a small cluster of bumps on my elbow about a week ago. Mildly itchy. No clue what the cause was but I thought it might be hives or contact dermatitis. It began blistering after about 4 days so I went to the walk in clinic the next morning. They gave me cephalexin 500mg for cellulitis.
Its been 24 hours since I began the antibiotics but its looking worse and I'm concerned the diagnosis is wrong. New rash appeared on the inside of my elbow on day 4 and on my finger yesterday. All on the same arm. The skin is swollen and painful to touch or move my arm.
Whats going on?
