Hi New to chat forum. I have PA, severe osteo in knees and fibromyalgia lichen planus,very mild psoriasis (44yrs worth) and hi BP. Just diagnosed recently with PA and osteo and have been put on MTX 25mg weekly, naproxsen, folic acid 5mgs daily and assorted other vitamins etc. I have had some excellent results from the 6weeks of MTX and neovisc injections in my knees that I feel like a new person. My PA came on like a hurricane so I am relieved to have relief from the pain. I have been lurking about for a while, surfing the net and am relieved to find this comprehensive site. By far the best one.
