I totally think you can be helped by a chiropractor, headaches are their specialty. I bet you have a pinched nerve in your cervical region (neck) and once you have an adjustment or two, you will be fine. It is sure worth looking into it, especially since you have asked your GP and dentist and neither can help you. Give it a try.
I totally think you can be helped by a chiropractor. It sounds like you have a pinched nerve in the cervical region (neck) and a couple of adjustments should get rid of the issue as headaches, etc are one of their area of expertise. It certainly will not hurt to try, especially since you have seen your GP and dentist and neither knows what to do.
Give it a try, you might be pleasantly surprised.
I found out what it was. Sinus headaches. They got so bad now I've got a sinus infection.. I thought it was a cluster headache or something. So many symptoms fit so many other diagnoses it's ridiculous
