About three months ago I began to notice a small oval shaped indentation in my forehead but didnt think much of it. Today I noticed the indentation is larger, a different shape and is a bit darker in skin pigment. I have a history of Migraine headaches, cluster headaches, migraines with vomiting and chills, sensitivity to light (even when no headache present) changes to vision, blurred vision both eyes at times, a weak left eye that tends to want to stay closed all the time but especially when tired, had Breast Cancer in 2007. landed on my head when I was four. No recent head injuries. I would appreciate your assistance with this. Oh ya! also have had a few sporadic sharp shooting pains in various places in my head over the last six months I would say. Just thought they were auras indicating a migraine on the way. Thank You
