Wow I am having nearly the same condition. My feet, legs, and knees hurt all the time. But it is worse in the morning, and I am stiff as a board when I get out of bed. It does gradually get better throughout the day. I am 5'6 160lbs. But it always still hurts, when I sit or stand in one position for more than 15minutes it gets worse. My muscles tighten, they become stiff. I can't walk down stairs (I can go up, my knees just make creeking sounds). This all started last May, when my right knee swelled up really big (no injury) then fluid traveled all over in my leg, mostly the way gravity took it, to my ankle. I had no insurance at then time, so I had some crutches at home from my Grandfather, I used those because I couldn't walk. It took a week or do for the swelling to go away. I was scheduled to be out of country in July for a month visiting family, so I went even with my leg bothering me (I could walk again at this point). I was there two weeks and got Shingles, I flew home with it and got trated for it. I still can't walk well, and all of my "old" injuries hurt too, like my pinky finger I broke in 4th grade. I strech still daily, and exercise even though it is extremely painful. It hurts so bad I developed a jaw clinching thing I do it constantly, that hurts too (but not nearly as bad). Any ideas of what the heck is going on with my body? Oh I forgot to mention I went to an orthopedic surgeon, and he told me to lose some weight, he sent me for an xray of my right leg, since that is where it all started, and I haven't been back. The xray was negative.
