on sunday i noticed the right side of my head, a bit behind my ear was numb and it went towards top of head. as of today it does not go up as high but it is still numb. i notice it most when i brush my hair. i have no bumps or sore spots. i did have a heavy night of drinking, i am happy to say though that i started aa meetings on tuesday & no alcohol since saturday night just before i noticed this problem. i went to sleep in my car that night and may have had sunglasses on my head, could those have put too much pressure on my head? i can't figure what would cause this, sorry to say i dont know if i hit my head or not and since there are no bumps i didn't think so. thought i would ask here before i panic and run to the doctor, i have no insurance and head tests are very expensive. i hope someone might have some ideas? thank you
