Yeah, that’s normal. I had the pain initially on my left side too. I asked the surgeon when she came around to check my wound in hospital and she said this is because they use the very far right or left of the wound as an anchor for the stitches, so the stitches can be deeper on one side to make sure they’re secure (something like that anyway 😂) completely normal though!
It’s normal to have that at one side, especially the side your wound is tired of at! My midwife told me it’s due to the damaged nerves coming back to life and being trapped in a little cluster. I’m 16 days pp and get this also
