I remember when I was getting wood for the wood stove 4 years ago, I was coming back out of where the wood was, and I slipped backwards onto a 1 foot high frozen hill, I couldn't breath, and didn't have the urge to, and couldn't move except for my arms, I managed to roll myself over with my arms, and that's when the severe lung pain and back pain started, I found that after a while, I could breath again, and stand up, I was very lucky that I didn't get knocked out, as I would be dead from not breathing!. rolling over relieved the pressure on my spine, But, I still can't do many things I used to do, even tying shoes or clipping toenails, and picking something up from the floor is slow and painful.. with the opioid investigations, doctors are too leery to prescribe pain medications that really work without side effects for long term use!..
