Poor you. Sympathise completely as I have been struggling with back pain for years and particularly since getting pregnant (my first).
I see an osteopath and IMT consultant at Balance Health on Caine Road

Ben, Alice and Carla are all great although they work in different ways. I started with Carla and she pointed me to different people in the practice as I went along. Someof the therapies are more aletrnative and some are more conventional. I gave everything a shot and have really felt the benefits.
Good luck !
