It's not easy and I can totally understand what you are going through. I had that kind of pain for the first day, but everybody is different. The RHS of my scar also hurt the most but that was because they had some difficulty getting DD2 out and tore all the muscles on that side (I found out later). The midwife told me the side the finish off the stitching is usually somewhat painful depending on how it has been done - mine was finished off on the LHS but it might be why your is sore at the moment too. I also had dissolvable stitches.

It does get better. The first days are the hardest. I know it sounds really difficult and try not to overdo it, but having blood pumping around your body does help with healing so if you can manage a very gentle short walk, even up and down the maternity ward a couple of times a day, it might help to heal things up a bit more. I don't know if you are getting time for it or not, but I think that was the thing that helped me the most. Mine was also incredibly painful getting up and down for the first few days, but once I was upright, I could take slow and gentle steps so I tried to get my movement back by getting myself mobile.

The important thing is to listen to your body though. If it feels like it is too much then it probably is and you need to take it easy. If your DH is around to help you out for the next couple of weeks, maybe ask him to help you out of bed too. My DH lifted me in and out of bed for the first couple of days (they didn't put me in an electronic bed mine needed to be manually cranked) and also for the next couple of days after I left the hospital. He got up in the middle of the night and got DD2 out of her craddle - which was next to my side of the bed and he put her back in it after I had fed her. I think it all made a difference.

I hope your recovery goes well from this point. It does get better and in a few weeks, you'll fell almost normal again. Just take it easy in the meantime and work at your body's own pace
