"I have had this for a few months now (2-4 months) and I have had bumps around my scalp. They come and go. I have not had such a bad itch recently but, I also itch around my body, although it's not horrible. I just want to know what I have."
I would try changing my soap to something like dove but it would probably be worth talking to your doctor about. dry skin is a common reason why people get itchy but it could even be a side affect of medication. the way you say it is more generalized to your scalp makes me think dry skin.
