Hi K.
I read the last 2 responses and they advise you to walk around and do some gentle exercise and that you don't need to take the pain meds , neither of them say whether they have been through the same thing.
I had an appendectomy last summer , I was 34 wks pregnant at the time , not sure how long between you getting pain and having a diagnosis was but that could make the difference. I went into hospital in agony after feeling unwell all day not knowing what wrong , after 4 days in the hospital and my OB insisting it was kidney stones they finally did an MR scan to find that my appendix had ruptured. I was taken down for surgery where they delivered my daughter and also removed the ruptued appendix and cleaned me up. My incision is vertical and 10 inches long down the centre of my stomach , I stayed in the hospital for 10 days after the surgery , they left the incision open so it could heal and close from the inside , I had to have it packed and redressed every day and for it to close took almost 3 weeks.
So what I am saying is that I did need the pain relief but I was no longer pregnant , yes it caused constipation which is painful in itself , I could not walk properly or upright for a few weeks and I was tired all the time and slept a lot.I also was not allowed to drive for 6 weeks.
As you are still pregnant then it sounds like your incision is not as big as mine so you should heal quicker , but you are right to try and move around as much as you can manage , and also try to eat foods that will help with bloatedness and your BM's.
I hope you feel better soon!
