Scalp pimple

I have severe pimples on my scalp.

It hurts every time I brush my hair, and it's quite stressful.

The hospital says that the scalp dermatitis caused by stress is due to fever.

Oh, this damn stress is always the problem.

Even though I am applying the medication received from the hospital, it doesn't seem to subside easily.

ㅠㅠ

Should I also switch shampoos?
