I have a raised rash on my neck in front, and a painful lump on my scalp behind my ear and the lump sometimes itches. Any ideas?

I have exactly the same symptoms! The lump behind the ear and the chest rash.. I went to the doctor today and he had no clue, said it was best to wait and see what happened next. Did you find out what was going on with you?

I just got a bad allergic reaction to a black hair dye. It started with the same lump and almost a week later I had to go to the dermatologist for a cortizone shot.

The Doctor said it can take up to 7 days for your body to react to a new allergy.

Do you have an itchy scalp? Is your scalp wet like an open wound? Do you have lumps under your skin on the back of your had and neck?

If so go buy a Peppermint Oil based leave in conditioner and leave it on your hair after you shower. It will help you make it through the night without itching. You can leave it in during the day to if you wear a head wrap or bandana.

And call a dermatologist to get a shot. My reaction took over a week in a half to develop so catch it before it gets worse.
