Talk to Dermatologist on Head Itching - Skin Problem

I have severe itching on my scalp. There is pain when I touch my scalp. Small bumps have formed. This condition has been ongoing for many months. Biocos Sache. Occasionally, I use Biocos hair color sachets on my hair. Avil and Dexa Injections. Two days ago, due to severe itching, I took an Avil injection and a Dexa injection. These provided temporary relief, but the symptoms have returned and are just as severe.
