@anamur-- Aside from the tips in the article, I recommend cleaning the area very well after bowel movements. Witch hazel wipes and pads are great for this. It prevents infection and also helps with the inflammation.
I had a lot of swelling around my episiotomy scar and I would put the witch hazel pads in the fridge and apply it on the area. It would reduce the swelling.
As for intercourse, it's not allowed until after six weeks. A friend of mine had serious pain during intercourse months after her surgery due to scar tissue. She had to have scar repair done.
