after an injury during a sports activity, I stayed 15 days lying, with back pain and muscle contraction. Then after once standing, sciatic pain. I saw a lot of doctor, pass MRI (herniated disc L5 S1), a doctor proposed lumbar fusion, another no. Then, I had infiltrations, then I saw chiropractors, physiotherapist, ... It did not change much, then I found the sarno books, then back sense, then this forum. I did the program, and I read a lot. In a few months my pain diminished, I recognized myself in the readings. I resumed physical activity, cycling, running, hiking, ... the pain has almost disappeared for several months. But, since a return from vacation the pain has gradually returned with very changeable symptoms, back pain, legs, right to left, tingling, muscle weakness, low back contraction. I suffered a relapse for 2 months, I can not control too much. I am not too physically limited, I run 12 km, I ride a bike. I feel better after physical activity, little pain during the sport.
