I also have PSA. I'm sorry but what I will write may not be useful for you

I was on various Biologics for 30 years and did very well. In Nov the one I was one stopped working and I have tried 4 others without success. I guess the TNF blockers are not working anymore for me. I met with my Rheumatologist recently and now she's saying that my symptoms, which is that in various places in my lower body , it feels like I'm on fire, sort of.
She said that I may have fibromyalgia because I have no swelling. This is weird to me, how does PA morph into fibromyalgia? I had some blood work done, so I'll see. I am planning to see a rheumatologist at Hopkins who only sees people with PSA. I think that if what you're dong is not working you should go see someone else for a consult.
