suffering from Arthritis

been suffering from Arthritis for almost a week...and I thought it's nothing major and i am soooo wrong....the pain started from my right knee then went to my left wrist and right shoulder... I couldn't even get myself dressed or write. n I wake up this morning my left hand was just soooo swollen.....LOL well I dun even know what exactly cause it, but right now I'm given a 4 days sick leave and a bunch of tests to do in order to try and find out the cause...man, this make me experience people who suffered this kinda of pain 24/7, before I didn't understand when the mature students complaint about their shoulders or back pain, but I guess I do now...n i'm also started to think what if i dun get to dance anymore.....it'll be sad but I also wonder what else can I do....em...I wonder......
