I had a similar pain, but it was on my left side. Seriously couldn't move for a day - it sucked - but the next day, it was much better. As far as pain relief, it's tough since you can't use a heat pack or anything like that. I just took it easy and spent most of the day sitting very still - fortunately, it was a weekend and DH was around. A warm bath might help as well.
Hope you feel better soon!
