Hi all, I was diagnosed with RA and fibromyalgia about 15 months ago. I was told that there us no treatment available for the fibromyalgia so my consultant is concentrating on the RA. I have recently been put on methotrexate injections as the tablets upset my stomach. So far, so good. However, I was also taking naproxen to help with the pain. My consultant advised me not to use naproxen but was a bit vague as to why. In the last 10 days, I have daily episodes of cystitis type symptoms with worsening lower back pain which feels very tender even to touch. My GP took a urine sample which tested positive for blood but did not show any infection. I have to repeat this next week. I was pre scribed antibiotics. I have stopped taking naproxen as I am concerned re my kidneys but really need some type of anti inflammatory drug as when I don't take any I am in considerably pain. Has anyone any suggestions please?
