Hi all, I am on warfarin for life after multiple clots in my lungs new years eve 2009, I also have chronic lower back pain (spondylitis & spondylosis) which I take heavy pain killers for twice a day. I was diagnosed with Graves disease a Year after my eldest Daughter was born (2001), and I had a partial knee replacement in March of last year, which has not worked and am seeking a second opinion on. Phew, there are many other things but I think that's enough.
