Use some witch hazel on it. If you have some gauze soak it and keep it there it may help with the swelling. I used the shower after a bm for a good two weeks but once the stitches fell out I now use the wet wipes. In another week you'll feel so much better.
I thought I was almost there but then sat having a pedicure and after 40 minutes in a padded chair I was in a lot of discomfort so a gentle reminder to still take it easy.
