Wow, I decided to google nuvaring and leg cramps. I haven't had a charlie horse in 11 years, but I had one two weeks ago and I have noticed my legs are always achey. I have rheumatoid arthritis and my other joints don't even hurt this bad. After reading this I took it out. I rather have long periods than leg cramps. Guess I will call the doctor on Monday and let her know. I can't take oral pills because it goes through the liver. This sucks. I just wasted 35.00 after getting the mail order people to drop the one prescription from 67.00 to 35.00. I am anxious to see if my leg cramps go away. :-)
