Had the above, with polyp removal and mirena insertion on Wednesday. I had similar done 9 years ago and I felt fine 2 days later. I was right as rain yesterday but very achey and my abdomen is very heavy today. Based on my previous experience I had hoped to go to the gym this morning but decided to skip it. I have a good pain tolerance and purposely did nothing yesterday as I'm usually over ambitious when I'm recovering from anything (I'm a frustrated and frustrating patient!). I know it's a piece of string answer, but how long would you give yourself to get over it?
