Welcome Tiffany! I love your quarter sheets! :)

Tiffany, I read your comment on the fitness challenge thread. I made a group for handicapped and disabled riders, I hope it is still there, get on it and you may find that there are people like you.
I have MS, and I am 59. Yes, I have problems, but woman, I do not have as many problems as you do. About your stiffness, I have had GREAT success with hemp powder with an arthritic Arabian mare. When she is off it she moves like she has sand in her joints, with it her movement is MUCH smoother. I use hemp oil when my joints act up. The Gamma-linolenic acid (GLA)in the powder or oil acts as an anti-inflammatory all over. Other sources for GLA are Evening Primrose oil, Borage seed oil, and Black Current seed oil. These are more expensive, but if you have to do drug testing the hemp seed oil/powder can trigger a false positive. The other oils with GLA do not have this problem.

Oh, I hit a key wrong. You can get all these oils and hemp powder in the natural food stores. Hemp powder is legal (no mental effects) in the USA and Canada for sure. I really hope this helps you, I've seen amazing improvement in the mare I ride.
