I'm very sorry to hear about the headaches. That stinks. I'm very prone to them myself and have different kinds. I've had migraines and tension headaches. You may have a tension situation going on. Are you going through a stressful time? Have any neck stiffness as well?
Hello~I know this was posted back in November, but I will give my opinion anyway in case anyone else has these issues and would like to know how to handle it.
It sounds to me like a pinched nerve or a vertebrae out of alignment. I would see a chiropractor for this issue, they specialize in headaches and have helped many with migraines and other types of headaches. He/she will take some x-rays, study them, and then discuss the findings with you. After a few treatments you should start to feel better.
