Yes that's right it's called Prolotherapy and a course of closely timed injections must be done to benefit ,it's been 5 years since my last series and it's only now that I can start to fell a bit uncomfortable from time to time.
I've always done daily stretching exercises and strength exercises to keep in tone . This ,like other treatments is not a cure but a pain relief strategy , but the pain is always there but with strategies such as these it can help to manage pain and strengthen surrounding areas to support the damaged area. Even when driving I do pelvic tilts almost unconscienctiously so I can enjoy a degree of health fitness.
one thing I did not mention before was that with lower back damage it can spasm the muscles so much that I developed tumors (non cancerous) in the pain area the size of half boiled eggs. A sports therapist used to massage me and burst them with his thumbs, I used to go home a wreck , but since I had the prolotherapy none have come back.
Always keep up exercise and never sit too long ,that has helped too, I hope this helps someone.
