Interesting. I get ringing of the ears fairly often, I get stabbing ice pick headaches (always scares me a bit that it's an aneurysm), and I get odd scalp feelings also. Man if I listed all the strange feelings and symptoms I get lol.... Yet my only concern at this point is lymphoma... Because night sweats speak louder to me than those annoyances that I've gotten used to. Anyways, point is, you can have these things and not have a brain tumor or anything like that. I'm one of those unlucky people who's hyper aware of their body. Every twinge, every itch, every pain. I daresay must people on this forum are. My therapist talked to me how some people are wires that way. Doesn't mean we are anymore prone to diseases, but unfortunately it's harder for us to ignore than most "normal" people. My husband fits the bill as a normal person. He hardly notices anything about his body.
