Six months ago I was hit in the back of the head, and probably received a concussion. For a month after, I was dizzy and nautious and all I wanted to do was lay down and sleep. I never went to the doctor, but did talk to a doctor friend after the fact and from what I explained he said I probably had a concussion. Since then I have had bad headaches, starting at the base of my neck, up the back of my head and then a migraine (migraines are not new to me, but they are different now) I started goin to a chiropractor about a month ago, 4 days a week. In the x-ray he took everything seem to have shifted to the right. It is a slow process, but I was beginning to have some hope of feeling better. He went out of town, and the 5th day of no treatment, my neck started stiffening, and I had a bad migraine, now 7 days with no treatment and I feel like I did 6 months ago. I have missed 2 days of work, I cant sleep, if I lay down and put any pressure on my head I get a shooting pain from the point where pressure is placed. I am dizzy, nautious, and very uncomfortable, my head hurts to the point of tears, there is so much pressure!...is this normal?
