Good point further back (sorry) - we are all telling you how to cure our back pain! But what else can we do. In my experience of my back:

1. "Been to the doc, who gave me anti-inflammatories and strong pain killers." This is essential the pain has to stop - you wont become addicted or resistant but you might get constipated.

2. If you don't have pain, then you have pain, find out what provokes it and stop doing it. It has been low chairs, lifting, washing up at a low sink, soft beds for me and tucking my trousers into my socks.

3. If you can find exercise that strengthens your back, that should help but it sounds difficult and could make things worse - Of this I have no experience.

When in pain find videos to watch, music to listen to, books to read and don't feel guilty that you are unable to do much. Just enjoy as best you can.
