You should have a blood test for the HLA B-27 gene which is an inherited gene.If you have it you may have ankolyosing spodylitis. A rheumatology dr. is the best to do the test. You could have had this and the wreck brought it out or made it flare up. AS will make you stiff. Good luck. I ahve the gene and I've had 2 back surgeries and I am very stiff.
