Last month I was diagnosed with Prurigo Nodularis, my hands, arms, ears, cheeks, chest, somewhat legs were itching uncontrollably. It was unbearable and nonstop. I took some consultation from a dermatologist and took medicine and got it stopped, but after 2-3 weeks it has started again and now those medicines are also not working as before. Please help the itch is uncontrollable and specially when it happens on my ears it happens so bad that even most times the blood comes out post scratching the itch.
