I had a chiropractic adjustment earlier today that involved my neck. I have had several similar adjustments over the past several weeks. However, this one was attending with some pain and tingling at the base of the neck - which lasted maybe 15-20 min. When I Googled "neck tingling after chiropractic adjustment" (or some such similar thing) I discovered an alarming article that disparaged chiropractic generally, suggested that neck adjustments are dangerous and can cause internal bleeding, and indicated that said internal bleeding can lead to strokes. This prompted me to probably have a panic attack. I now keep focusing on my neck and worrying that I am bleeding internally. Of course, the worrying has made me feel a bit light-headed. Although, when I take my mind of the worry, I do not seem to have any dizziness. I have no idea how rational this fear is, however. To put it differently, I do not know how realistic a danger I face. I am 36 years old, fit, active, no health problems (to my knowledge) apart from "seasonal" allergies. My main question is: What are the symptoms of internal neck bleeding? Should I be concerned? What tests (if any) can detect internal neck bleeding, were there any to detect?
