for the last week and a half i have been having pain in the back of my head in my forehead and in temple area, sometimes it feels like pressure, and i get lightheaded/dizziness off and on. some days are ok some are not. i went to the doctors and she said i have a sinus infection. i dont think thats it because i didnt have alot of the dizziness/lightheaded when i had a sinus infection before. i get numbness in my hands especially at night when i sleep and it hurts. its done that for years but more often lately. i dont have medical insurance so im limited on what i can do. does this sound like thyroid problems? can someone help me please!!!!
