What could be causing this sores on my scalp they hurt really bad..
Could be psoriasis, could be caused by dry air in your home, if you live in a climate that requires you to use a furnace in the winter. However, if you're bothered by it so much, you really should see your Doctor.
ringworm usually itches. shingles maybe? allergy or burn from hair color/chemicals ?
