I have been having headaches off and on for about 3 weeks now. I suffer from bad sinus and I live in Ohio. I wake up with a headache, I go to bed with a headache. I have notice that it's very hard for me to go to sleep at night. At times it fills like someone has hit me up side the head until I take some aleve or something. However I have been under a lot of stress lately. Is this something I should rush to the er for? Annie.
