Hi All, I am new here and only discovered TMS a couple of weeks ago. I have been struggling with lower back pain for over 3 years. I was told I have a very minor disk buldge at L4-L5 but otherwise main hypotheses were - weak core, one side of the body tighter than the other, one leg shorter than the other, shallow breathing etc. Needeless to say, I have tried physical therapy, swimming, massages, acupuntures and nothing helped. My pain is at its worst in the morning and after exercising, which meant I had to limit my two favourite activities - tennis and running. A couple of weeks ago I discovered Dr. Sarno's book and immediatelly felt better (I am the perfect TMS candidate). After that I read Steve's book. I started to run and play tennis again but the lower back pain has got much worse. I keep on thinking that it may be due to my lack of understanding/doubts about one particular question. I read everywhere that you know it is TMS when the pain from sport does not go away in the normal timframe. However, what if the particular move/sport just aggravates certain muscles/nerves every time? Many people have pain in TMS moving unpredictably, but I know it is always worse after sport. Thank you for your advice.
