Give it time and you will heal, I had internal stitches which hurt like hell, at one point I'm sure I popped a couple because the pain was so intense, I also had bleeding and discharge which went in time, infact I think the popping of a few stitches hampered my healing time, I still have a bit of discharge now and then especially after a tricky BM, but after 4 months I can say I'm healed.
Just be patient and vigilant, take good care of your ass and you will get there in the end.
