I had sciatica a few years ago, went to phsio etc. one even told me to sit on a squashball. (I hope laughing doesnt hurt). But nothing was doing any good.
Thats when i discovered the Bowen technique, if you can find a pratitioner in your area I wholeheartedly recommend that you try it. Mine was using a room at the local health centre and it was my doctor who suggested that i give it a try when all else failed.
I've been back for frozen shoulder treatment and also friends have been for many more ailments it really does work. Either way hope you're feeling better soon.
