Hi,
I am 41 years old. I was diagnosed with a reaktive arthritis 6 years ago, started off with a salmonella and campylobacterial infection. In and out from emergency departments. Treated with predisolone and steroids injections. Recovered after 5 month. I have always been fit (special forces), was not used to be this weak. After 6 year received new infection, started after flued like symptoms (excuse me swedish spelling), Refered to specialist rheumatologist, now on 4 sulfasalazine 500mg x 2 x 2, and plaquenil 1x2 daily without any improvement. I have also received steroid injections when flare-ups. False feeling better for 3-4 days, and then back to "normal". Awaiting further treatment, I think metrotrexate. Any other with this symptoms? Also have had iritis every year. I would be glad if anyone with this symptoms could give me any
treatment sugestions or reveals.
Good speed,
