question: I have what i think is a cyst on my forehead. I got into a fight and was hit in the head and since that happened there has been a bump of my head. Doctors have told me its a cyst but i have also heard its built up scar tissue... The bump goes from being soft back to being hard im guessing when its irraitated. Do you think this is a cyst? Ive tried poking it with a probe but all that comes out is blood.
