reactive arthritis -salmonella poisioning

F75. Previously healthy, mobile. I got salmonella poisoning at a breakfast place. Confirmed. 5 weeks later I started to hurt all over.. No history of arthritis. Confirmed as reactive arthritis-only 3 sources- HIV/AIDs, IBS, food borne illness. Mine from the latter. Confirmed by Infectious Disease Specialist. Rheumatologist prescribed Celebrex. One pill and violently ill. Now taking Advil. Not helpful. PCP has no clue what to do next and rheumatologist seems uninterested! Trying to do medical research [used to be called Reiter's]. Has anyone had it or had it treated successfully?
