Yes. It started as a pain in the bum and then travelled right down the back of one leg, where it remained very painfully and inconveniently for two years. My doctor put me onto a heavy-duty painkiller which did the job, but this was a long time ago and there are very much better ones these days. The brand name was INDOCID, but there's a medical name behind it - one pill saw me okay for around ten hours, which was great. Your doc should be able to recommend one that acts like it, but is more up-to-date. Moving around or sitting around - didn't make a jot of difference to me. I still rode and went swimming once the painkiller kicked in - but without it, all waking hours were just pain. Don't forget it's a nerve which is being nasty, not muscles or tendons. Thus, hot baths, massages, etc., were a waste of time, and the one session of acupuncture I tried didn't make any diff - although it might to you. The good bit is that it got bored and eventually faded away. Good luck.
