Hello, I have bald spots on my head and there are lumps on there. I have a big one the side of two half dollar coins next to each other and a couple dime size ones they sometimes pop during the shower and a thick yellow-tarnish substance comes out followed by thick blood. Sticky/slimy texture. The big one is very tender to the touch and I can't sleep on it. It's beginning to have a throbbing feeling to it. I went to the my family doctor and she said its a cyst but she didn't do any tests on, it just a quick look. Is there any other possibilities? She put me on some antibiotics to treat infections and had me lower my blood pressure through meds and diet in order to put me into surgery. This far, 5/10 days of antibiotics, the lump is showing no sign of getting smaller like the doctor said. Please help. :(
