rheumatoid arthritis
"I've taken sulfasalazine for four months (1000 MG twice per day). It took at least six weeks to become effective, but combined with Etodolac, an anti-inflammatory, I have had good success with controlling a mono-arthritic knee that had been diagnosed as rheumatoid arthritis after almost 20 years of problems, various surgeries, etc. I worry about side-effects, but the pain and extreme swelling is  controlled after many years."
