I live in the UK and have had no help from any of the medical

Hi Sandra
I just wanted to offer you some sympathy, I too am in the UK and it is like being on the slow train to nowhere at times.
I have found great benefit from Alkaseltzer but like Mrs D use it as a back up when things are really bad. I keep it for bedtime and it eases the pain so that I can get to sleep. Epsom salts in a luke warm bath also helps but you would need to make sure the water isn't too hot.
Good luck
