Lower back pain could be kidney stones, although they tend to hurt more around the actual kidney area of the back, but could radiate pain through out your back area and front of the body.

I think alcohol does make this worse in general. You should probably avoid partying and getting piss drunk. I know it sucks to be sober all the time, but for some reason i think there is a link between drinking beers and EP.

Im curious as to what the homeopathic doctor did to help you?
