no

I'm a 72 Yo male, who likewise has had AS rulled out by Rheumatologist's exam, and a NEG HLA-b27 gene test. Sacroilitis in both SI joints. OA in both Knees, the right is Bone on Bone and will need replacement. My Spinal maladies have been diagnosed as Spinal Spondyliosis with Facet Joint Syndrome (facet joint arthritis), a number of sites of Mild to Moderate Stenosis in my entire spine, Cervical Instabilities and Loss of the Curve, and very thin spinal discs from Degenerative Disc Disease. I have suffered for decades since my early 30s. I fractured my right Femur in 1966 playing HS Football. The right leg is 1" short as a result. That Trauma has wreaked havoc with my body's physiatry - the leg length discrepancy was left Unaddressed by the Ortho Dr in 1966 when the Body cast came off. Despite the fact that there has ben no diagnoses of AS, the conditions I do have are very consistent with what has been explained here. SI Joint Inflammation is the Ground Zero for many Spainal issues. As my Rheumatologist explained - it all goes Up From There. There is no cure. I take many supplements to combat Inflammation and only ADvil / Tylenol to deal with the flair Up days. I got advice from a carpenter who had lots of srthritis : take 2 Advil in combo with 1 XTra Strength Tylenol - it works like a charm for me ! Advil is an NSAID, and Tylenol deals with Referred pains from the brain nervous system.

They best not tell me I haven’t got it as i have every thing inc HLA B27 gene positive

Its expensive thats why for treatment
