I am 50 yr old female. I am having a spot on the right side of my forehead( size of the palm of my hand) that is very cold an painful it hurts to my brain. It started about a month ago. it comes an goes several times a day. an on the left side of my butt cheek I am having repeated hot spots that come an go out of no where .I actually feels as if someone is burning me with a lighter. They both started to affect me around the same time but the hot spot happens a few times a week. the col spot on my forehead happens several times a day. What is causing these problems. are the cold spots on my head a sign of a tumor or something
