I was told I had AS. I have the same symptoms. But the doctor did the blood test for HLA-B27 and it came back negative. Others have told me not to put a lot of stock in the blood test because a lot of people have AS that test negative. I can't get in to see a rheumatologist until February. The orthopedic doctor has me scheduled for an MRI on my upper back and neck Monday. Will an MRI detect it? Will an orthopedic doctor recognize it?
