So Ive been feeling sharp pains in my head every once in a while in my head, they only tend to last a couple seconds. they don't tend to be in one spot. They tend to jump around all over my head, sometimes in the back and sometimes in the front. I dont have nausea, vomitting, blurred vison or any other symptoms. My question is could this be a symptom of a brain tumor at all? ANd what are my chances at my age and history of getting one? I am 21 years old and exercise regularly, also I checked and I dont think I have any family history of cancer at all.
