I have chronic pain...I was in a bad accident yrs ago. the last two years I have noticed a change in my gate, I get dizzy, sometimes I feel like I will fall on my face. I can't pick u things without feeling like my hands are going to break...they crack and pop, (between my knuckles are swollen), my right knee, my feet, feel like they are going to break when I go to put weight on them. While sitting My neck hurts so bad my head feels like it is going to fall off of my shoulders and hurts like crazy(my neck and shoulders). Like right now and I haven't been typing for twenty minutes.
