I have 4 sores in my hair line on the back of my head. I have had them for about 8 months now. My doctor gave me antibiotics for them and they cleared up, once I was done with the antibiotic, a few days later they reappeared. They aren't itchy, painful or scaly. They just feel like at times they are liquid filled and other times it's blood. My doctor said it was cellulitis, but I seem to disagree. I don't know what they are or why they will not go away and stay away.
