The key thing is to avoid flare ups. When a nerve starts to give off a pain signal, if you can stop what you are doing, and not exacerbate it, then the pain often fades again. Unfortunately sometimes a whole branch just kicks off, and this will eventually fade, but may take some time. Coming to terms with this is not easy as it can mean days just sitting down, but that is the choice you have to make if you have this badly.
