If you haven't heard of IMS here's a great article that explains it really well:
I wasn't having any luck with my back even with physio, stretching, icing, resting - all of that and I still had enough pain to keep me from being able to teach my classes.
Then I went to a new physiotherapist at Treloar Physiotherapy (Steve Wong) and he did IMS on me. It was super uncomfortable to have it done and I was sore after, but the next day I had NO pain!! It's been almost a week and I'm still almost completely pain free! I'm going back for more on Tuesday.
If you suffer from back pain you have to try IMS!
