I have had symptoms of AS for 10+ yrs and was finally diagnosed last month. For some reason, my lymph node in my neck on the right side got severely swollen and at the same time my back and SI joint started having problems too. When the swelling in my neck went down, so did the AS symptoms. Then the swelling came back and I started hurting again. My doctor doesn't think it's related - just wanted to know if anyone had this or if this is something else....It just started doing this last Friday.
