Fibroid Degeneration Pain

I'm just about 16 weeks and have been having very painful cramps which have kept me up for two nights. The first time this happened I was 10 weeks and I went to the ER. They weren't able to do much except give me Tylenol and told me to take it easy. When I told my OB what happened he said that it was probably some fibroid degeneration. I have about 7 of them ranging in all sizes so I knew that this may be an issue. I don't have any spotting just very bad cramps that come in waves. Has anyone had similar experiences and what did you do to deal with the pain?
