Since everyone else is posting their problems, might as well post mine too..
I hurt my left shoulder about 32 years ago, and it's been messed up ever since. Supposedly, I have an impingement, with possible nerve entrapment. It used to hurt so bad sometimes that I couldn't even do anything but sit and groan. I went to therapy, and it got much better, until the therapists talked me into doing cold packs along with heat and ultrasound, that made it worse than ever. I have full range of motion, but any outward "swing" hurts quite a lot, and if I have something more than 5 pounds in my hand, a "swing" feels like a knife has been stuck into my armpit. In general though, my left shoulder is now my "good" one. I hurt the right shoulder in a fall 6 years ago yesterday. A stumble turned into a life changing disaster. I started to turn my left ankle as I was stepping up from a parking lot to a sidewalk to enter a carry out. I tried to save myself from a sprained left ankle and I planted my right foot, and my leg arced over and my right knee was the "hammer" that slammed itself into the sidewalk. I'm a big guy, so between my weight and the forward motion, there was a lot of force involved. It made a huge CRACK, and it went dead, there was zero pain in the knee itself. My only original pain was in my right shoulder. I had torn it all up when I put my arm out to keep my face from slamming into the sidewalk. I had torn my bicep, and a bunch of other stuff. The doctors told me that if it happened to almost anyone else, their collarbone would have broken, and it wouldn't have been so had, but more than one doctor has said I have the thickest collarbones they have ever seen, so all the force of the fall went into my shoulder and upper arm. My shoulder would pop out of the socket and "float". I could lift my arm up to about shoulder high, but lifting it higher or with even just a couple of pounds caused amazing pain. I was urged to have surgery, but with my problems listed below, I passed on it. Smart move it turned out.
My main problems are my legs and back. When I fell, I crushed a nerve in my knee, and it was almost totally dead for over 3 years. It came "back to life" at 2am on Dec 2, 2010. Even the way it woke up was odd. At first, it was a minor throbbing that got worse and worse, to the point I was about to call 911 and go to the ER. But when I stood up to go to the bathroom, the pain stopped and it was obvious my right knee was better than it had been in over 3 years. Therapy was a disaster, I hurt my left knee twice, going to the ER both times, and the second time, I totally tore off my quadriceps tendon from my left knee, along with tearing up the muscles in my thigh, just like I had done on the right. Between both knees being messed up, I have major back issues, and like everyone else on my mom's side of the family, I have arthritis in my neck and spine. Standing still without leaning on something is torture, and just doing normal stuff around the house is impossible.
But other than that, I'm doing great!!
