After plenty of online researches i found this really useful website.
I have had low back pain since 2007 now. Now i'm acknowledging it has become chronic pain. I never had any problem until 2007 (i was 27 at the time) where i overtrained at the gym and had a major episode of lower back pain. From then on...
I feel the pain mostly on the gluteus (especially the left side), hips and all the area around L4-L5. Most of the pain come when i sit down, and i have to force myself to stand up as long as i can. I took X-Rays and MRI and there's no sign of major problems, only the facet joints seem a bit deteriorated but they told me it's normal giving my age. I also i have a bit of scoliosis but it seems it's irrelevant. I have been told my spine is straight and it's a bit of a problem. Still i feel this doesn't justify all the problems.
The back pain is affecting my life very much and i don't know what else to do. I quitted football, snowboarding, swimming and a lot other sport activities i used to do. I have problems travelling because when i sit down too much i have this severe episodes of back pain i cannot control. My social life has worsened.
I saw chiropractors, osteopaths, physiotherapists and orthopaedics, it's very expensive. Everybody somehow agrees it's because i have no core muscles, my spine is straight, i'm very skinny, and have fairly bad posture.
However, i started about 4 years ago to regular exercises, every holy day: yoga, pilates, specific stretching and back exercises, i wear feet insoles and i just bought a back support (which i don't really want to use). Still, for a nothing, i get into this episodes of back pain. Actually there isn't 1 day that i wake up fine. I rest: pain, i work out too much: pain.
I know that many people suffers from terrible bad conditions, i just wonder why i have all these problems if the exams show there's nothing serious in my spine. I'm only 33 and this problem is definitively affecting my life psychologically.
