you dont give much detail but i used to have a very bad itch and would wake up with bloody hands where i had scratched myself to peices. I was treated for many years with anti depressants and antihistamines but only relief was from sitting in a very cold bath until i was numb. I saw a new dermatologist who said i had lichen sclerosis and gave me elocon ointment, it cleared up in 2 weeks. Might be worth seeing a dermatologist.
ive been using the same soap for a month and this has only happened recently nothing has been rubbing it that i think of
I am not really sure...but maybe somehow the area is being rubbed and its irritating or ....perhaps allergic to laundry soap?
