I've been attending massage therapy sessions for my back pain for a while now. I'm having weekly sessions with my therapist and its helping. Does this count as exercise? Should i do any other simple excersices along with this ? or should I increase the number of visits to my therapists ?
No, massage is massage and possibly manual mobilisation of "sticky" bits of muscle tissue. A good physiotherapist may well provide some suitable physio "exercises" - but you can't really do them until any spasmed muscles have been dealt with and they are in a state to be able to be "trained" - which is what the exercises are aimed at achieving. The exercises build up the strength of the muscles to help avoid the problem recurring.
I'm in the same position - having massage therapy but it is from a physio and at the start she did mention something to build the muscle strength. In the meantime she is still finding muscles in too bad a state to exercise! I used to do Pilates until I moved here - that did make a major difference.
