My 2 year old son has had an ever changing skin problem for 2 months now. We have been to 4 different doctors and each one has a different diagnosis. His skin does present differently each visit however, so we are getting really concerned. Started 2 months ago with about 3 blisters on his leg(not close together). They increased in number over the week and developed a ring around them about 15cm across. We were given antibiotics for Impetigo . 2 weeks later(and on holiday in a warmer climate) spots reappeared, with a small black hole in the centre - looking like scabies . 2 days later they had swollen up(and looked like welts) and covered his face arms and legs and started to ooze clear liquid. He scratched the scabs so they now also bled. Back to another doc who thought it might be Papular Uticaria and insect bites that were getting infected. More antibiotics and antihistimine. About this time the palms of his hand looked really red and swollen almost like a burn. Back home and the spots are slowly clearing although there are thousands of tiny bumps(like small pimples without the white) covering his arms and legs. His palms are less red but are peeling. Does anyone know what it could be?
