I first read 'Healing Back Pain' five years ago after having sciatica for two years. It healed within a couple of weeks and I was amazed to be able to run, walk easily and return to a normal life after having to alter a lot of my daily activities to accommodate the pain. Since then I have suggested to many people that they read the book and I have re-read through the principles online whenever I have felt a return of the pain. I have only felt the occasional twinge over the past few years and it has gone within a few days. Then three weeks ago I felt a nagging pain in the back of my leg which then felt a lot more painful when I was sprinting during a run. It was very sore so I stopped running, iced it and went home. The next day there was no pain at all so I put it down to TMS. However I was due to compete in a running race a few days later and felt a slight twinge during warm up so didn't take part in the race. I've took two weeks off from running in case it was a hamstring strain, because I didn't want to tear a muscle (which I have done before). I began getting very different pain then, rather than pain in the area where the muscle hurt, I got shooting pains up and down my foot, lower leg, upper leg and buttock, just the same as the sciatic pain I had years ago. This made me suspicious it was TMS again. I went to a doctor, who diagnosed a hamstring strain and suggested a couple of weeks off running. I played it safe and stuck to two weeks off running plus have a rehab regime of exercises from the gym, then returned to running one week ago, gradually. It was fine during this past week and once I started running, the shooting pains disappeared. However this morning I went for a run and had to walk instead because I could feel pain in the original place in the back of my leg. Now those shooting pains/sciatic pains have returned again. I feel so low because it reminds me of the time before when I was in pain. I know I should probably just go out and run, forget the rehab exercises and get back into my normal regime. However I know I need to do journalling work etc because I have had a number of significant life changes over the past six months and if ever there was a time for a TMS recurrence, this would be it. I'm glad to find the SEP because I know I need to revisit the principles of TMS and just the act of writing this account makes me see how likely it is that the pain is TMS.
