I've had neck and back problems for 12 years and been prescribed voltarol and diclofenac. I found they were okay as anti-inflammatories but made little effect on the pain. Codiene is a great painkiller but doesn't solve the root of the problem. Mine was first caused by whiplash but has been bad in recent years due to RSI. Sitting at a desk all day and getting stressed always trigger it off.
I've had physio and accupuncture on the NHS but, like with the doctors, the standard line has been 'it will clear up given time'.
Personally, I've paid privately to see a chiropractor who is worth her weight in gold.She has always got me back up on my feet within minutes, without having to wait the weeks doctors and physios expect.
My chiropractor gave me sheets with exercises to do, which were far better than those given to me by my doctor and physio, and I feel like she's been far less dismissive of my problems (perhaps, cynically, because I'm paying her, but I truly believe she has far more knowledge than the NHS practitioners I've seen).
Focusing on how to prevent the problems in future has made me realise that my back problems are something I can take control of - and only my chiro has given me the skills to do this.
Sorry to hear you're having such a tough time. I totally understand - last time my back went I couldn't move for two weeks and had to have people coming round to help me dress and cook etc.It really can be disabling, but I can't recommend chiropracty enough.
And the fact that your partner put his back out while at his desk suggests that an RSI type injury could be aggravating the problem.
Hope it all works out...
