Chronic back pain for decades. About 15 years ago, read about sleeping with a pillow under my knees. Tried it. Now, no matter where I sleep, I have a pillow under my knees... if sleeping on my back... or between my knees if on my side. The "pillow trick" has most certainly helped provide many nights of good sleep that I would have missed if it was not there.
Also have a very good friend who just retired from owning a jewelry store for years. A few years ago, his back had almost put him out of the business. Standing on hard surfaced floors all those years had taken its toll. He had consulted with surgeons but did not feel ready to take the time of for surgery and recovery. Happened on an article about the Laser Spine Institute. Thought he would at least go for a consultation. He and his wife drove to Tulsa on a Monday morning for an afternoon appointment. Stayed the night and had the laser surgery on Tuesday morning. Released within hours of the surgery. They remained in the hotel room overnight on Tuesday and drove home Wednesday morning. Zero pain from then on!!!!
