I have had really bad headaches for about 10 days now. I went to my family doctor and he put me in the hospital to run tests. He done a catscan on me and the result came back benign lytic lesion on my skull. Both the doctor and neurologist said it is nothing to worry with. I am wondering if any one out there has a clue what this means. I have been on the enternet looking this up and I can't find anything. Please help.
