I think you are wise to see a doctor, it is best to find out what is wrong before things get out of hand. Please let me know how it goes.
i think i'm going to see a doctor. My mom is a little reluctant thought. She kind of thouught it could be from birth contorl pills, but it happened before i took them, so it wouldnt fix it. someone told me it could be Neurocardiogenic Syncope. I'm not sure..my neck is feeling better, still a little stiff.
Please see a doctor about this. It could be hereditary, heart related, or a host of other things, I would not let it go on too long.
Also, along with the doctor, see a chiropractor, if your neck and back are out of alignment you can have these types of problems as well.
Best to have all bases covered.
