As per your clinical history, most probably the disease you are suffering from scabies
infestation !! The scabies is caused by itch mite, which makes small burrows on skin of wrist and ankle joint areas, causing SEVERE itching
, and irritation in these areas, and also causes allergic bumps after few days.
You are kindly advised to get yourself examined your lesions from a nearby General Physician. As far as treatment is concerned, the disease is easily treatable by once or twice application of permithrin solution or benzene hexachloride lotion, and strict cleanliness of cloths.
hope my info helped you
