My spine feel like it's grinding together? its been like this for a few years now. pcp did bloodwork and found nothing, they insist it's got to do with my psych meds. i'm in general pain all day and went through a lot of tylenol this summer?

Usually blood tests shed little information on the cause of spinal pain. I don't see any relationship between spinal discomfort and psych meds. Get a proper evaluation of your spinal problem by consulting an orthopedic specialist or be seen at a spine clinic. Appropriate testing will be done in order to make a diagnosis and advise you about treatment options which may include physical therapy.
