I have a lower back injury, and do not know how it happened.
I have had lower back spasms in the past. About every few months that will last only a few hours.
This time i felt fine, until i bent over and it felt like a knife was stuck into my lower spine. Paint at 9/10. At that point it was very painful to stand back up. Throughout the rest of the night movement in any way was painful, and it was impossible to get comfortable in bed to sleep.
The pain is not as severe today, about a 7/10. But movement in any way is very hard and painful. The pain is located on my lower spine, and the muscles right around the area. Occasionally, the upper part of the butt muscles feels like it is pulled.
