The other day I went to get on my horse and I was already off the ground when my right knee popped and I thought I was going to black out. I had to get up on my horse cause I knew if I came back down on that leg then I would fall. I rode down to the bus stop to wait for my son and it started feeling better so I started to ride for a while but it just went to throbbing so I came back to the house and let my son ride. When I went to get off my horse my knee popped again and OOOUUUUCCCHHHH!!!!! It is still stiff and every once in a while I'll step the wrong way and it hurts again. My wrists are very weak too and especially my left one if I lift something the wrong way it screams. Is this part of the FM? I know that I have arthritis in my lower back but I was checked for RA 2 years ago and was negative. If it is the FM is it like attacking my joints? I haven't read anything about it doing that. I've read about the muscle weakness which I definately have. My finger joints hurt all the time too. Especially now when I am typing. My fingers also swell and my ankles hurt and swell and even the bones in my feet hurt sometimes. I feel like I am falling apart!!!!
