I’ve experienced some other symptoms on certain days where I sleep less I feel dizzy Some days it’s a lot worse then others Tylenol does help it yes. Some days when it’s bad my jaws hurt as well. Feels like almost if my brain is squeezing out of my head Like some pressure I talked to my doctor he said it’s tension headache this and this I’ve been getting run arounds I’m tired living like this. 2 days ago I experienced throbbing headache on top of my head and back of neck towards neck went to er they told me it’s a migraine I felt better today but I went to the gym felt fine the whole day lifted weights my headache is back It feels intense like pounding on top and ache on the back end of my head I’m not sure what it can be Maybe my pillow? Please help me if you can!!! I am scared I have a brain tumour or something. Gonna go to the er again and bug them thanks.
