My husband has a severe rash on his arms from the elbow down and on his legs from his knees down, he has been to 9 doctors, however none of them could give him an answer. His legs swell and break open they are red and severely itch. When he scratches them (legs and arms) the skin comes off and he bleeds. We are truly at wits end and he is going crazy.
Hi, Perhaps he has a sort of edematous dermatitis. Itching, excoriations and chaffing are signs of that. I suggest him to use a moisturizer frequently.  In addition to this I suggest him to use a potent topical steroid, e.g., either clobetasol propionate 0.05% ointment or clobetasol propionate ointment 0.05%, twice daily for a few days. He may also take an oral antihistamine, e.g., Tablet Cetirizine once a day for symptomatic relief from itching.  Hope I have answered your query. Let me know if I can assist you further.
