I had an attached photo of my infection. It is occurring from my childhood. I tried solving it many times by medication but it always comes back after a while of stooping meds. Anti scrabies, fungal, parasitic & itching all works but after stopping them, the bumbs like pimples on my skin occur again. It leaves a black/brown scar after it heals. And sometimes leaks white fluid or blood leaks. Itching mostly occurs at night and when I wake up, I find many areas on my hand and feet mostly skin is cut, and my nails have blood stains so it is clear I do them at night. These things only occurs on places that is uncovered e.g my hands, feets, neck & face. When it happens on behind hands & feet it hurts a lot but feel itching them. It mostly occurs after mosquito bites. I don't know how to cure it, any help in identifying what it is?
