I had a really weird blotchy skin rash on my calves and back of thighs one summer. The doctor said it could be a fungal infection and I should treat it topically with Selson blue. That didn t work, so I quit doing that. Ever since this mysterious rash, I ve noticed that my legs, such as inner lower legs, get red and blotchy after I take a shower with really condense redness and warmth around my knees especially. The redness goes away 30 minutes after the shower but keeps returning after every shower and in different locations of blotches. I ve tried to treat with triamcinolone with no such luck. What could this be?
Hi, The rash could be a ringworm or an urticaria (hives). Ringworm usually does not disappear after shower. Whereas, urticaria could be due to various causes such as Chat Doctor.  You should find the cause and to avoid the causative agent. You could take an antihistamine tablet for symptomatic relief. But, I highly recommend you to consult your Dermatologist to confirm the diagnosis and to initiate the treatment. Hope I have answered your query. Let me know if I can assist you further.
