I had a pimple like thing on my scalp.It used to itch a lot.One day,I accidentally scratched it too much and it started to bleed.The bleeding stopped and it was replaced with a scab.I have a scab picking habit.I uused to pick off the scab whenever it formed.I kept picking it off and it kept reforming again.It's been a long now,it didn't heal.When I picked the scabs off clear liquid oozed from there.It doesn't gives me any trouble though,no itching,no pain.Is it skin cancer? I'm scared.
I would go to your GP and get it checked as it keeps coming back. I have had skin cancer 3 times but that was from moles but I was told that if I had a sore that didn't heal I needed to get it checked out. so I would book an appointment with your GP to be on the safe side.
