I began having LBP in the summer of 2012. I had no injury or mechanism of injury, the only possible factor is that I had just begun running several miles for the first time in my life. It began as only localized pain in my left low back at the SI joint/PSIS area. Over the next few months it progressed to pain down my leg (only in calf, not thigh) and muscular pain on the left side in the muscles throughout the spine. I have been to countless orthopedic MDs as well as PTs and chiropractors who all have said that they see nothing wrong with me, or some who said my SI joint was the culprit with it being out of alignment. Treatments for these things have been without relief. I now take Neurontin everyday to try to keep the pain in my left calf under control. Last spring I even had the SI joint injection with fluroscopy without any real relieft, but I still feel the left SI joint is the origin of the issue. I can feel the left PSIS protrude posteriorly and snap in and out of place when I stand up from seated. Since this issue is very chronic now I have pain in my upper left spine as well (both thoracic and cervical) that is unresolved with massage and chiropractic treatment. I feel very hopeless. I am so young, and am I going to have to live with this pain forever? Each new doctor I try just orders more of the same expensive tests which lead nowhere, and has put my family into extensive debt. I feel my life is very limited now, I am unable to exercise, sleep normally or do things normal young people can do. I have to take care and precaution to try to sleep in the most ideal condition for my back (pillow under left side) and cannot tolerate sitting or standing for that long. I would love to get back to running again, but it seems impossible now as I cannot even live one day without pain. I have had pain every single day for the past 3 years and the thought of living this way for the next 50 or 60 years makes me almost not want to live. Can anyone help?
