Why do scratching causes bleeding in the head?
Patient: when i scratch my head, i get white stuff on my head, and when i scratch a little TOO hard, i get blood under my nails.. why is this happening to me?? and i don't know why, but i'm addicted to scratching my hair ! but when i wash my hair i don't dandruff and as soon as i touch it, they appear ! Doctor: Hi,From history it seems that there might be having some scalp skin infection like eczematous dermatitis or dandruff infection giving rise itching and soreness.Consult dermatologist and get examined.After proper diagnosis plan of treatment can be decided.O)k and take care.
