I had two infections between Dec.2012 and March 2013. I was treated with an antibiotic and felt fine. I take a Naprosen, Robaxin, Embrel 50 once a week and Vicodin once a day for my Ankylosing Spondalitis. I have been on these medications for 20 years except for the Embrel. It has only been 4 years. I drink alot of fluid, weight 127. BP 118/60 and I exercise regularly. My older brother and two of my Paternal family members have had kidney stones and kidney cancer.
