Have i got a brain tumor? am very stressed about that.?

A legitamate fear that should be adddressed to a Doctor. A general rule of thumb though. If it orignates at the base of the skull and you can press your finger into it and cause pain EXACTLT like your heasdache, even radiaing to the actual location of it ie frontal, temporal or behind the ear, it ain't a brain tumor. If yo cant easily find it and if pressure does not relieve it, you may actually have to check where the muscles attach to the shoulder blade. get a friend with a pointy elbow to apply pressure. if you can't find it, there are just too many other causes of HA including stress, depression, anemia, vision etc. See a Dr.!
