There are some rheumatic diseases I never heard of. But now my aunt has a rheumatic disease and I have surfed the internet a little I know all about it. And it is no fun at all. But what I also did find was a special cream they use to relief the pain a little bit. So I ordered that right away of course. I think it will help my aunt to feel better. She is such a sweetheart so I would give anything to help her get rid of her pain. She is such a aunt who is at all the family events and knows you as well as your own mother.
