WELCOME (to the club), LuvlySerenity7:

Yes, You have AS.

Sorry.

It is just that simple from Your constellation of symptoms.

I would get the HLA B27 test done, if possible (a positive result means You absolutely have AS and a negative result only means You do not have ONE of the many genes responsible for AS, but You almost certainly still have AS)

NSAIDs made me worse, long-term but were great temporary relief albeit not worth the consequences.

Good luck with treatments.

A physician who cannot diagnose AS can open a book and treat (mis-treat) AS...well through "benign neglect" You will eventually have SIJ fusion. The focus should be how to AVOID that damage in the first place!

NO rheumatologist can do this for You.
Only YOU can,

John
