D.R.
There is another question like this on Mamapedia from 2008 from someone named D. B I was trying to cut and paste it for you but it wouldn't let me. I had an episiotomy with both of my kids. My first one was 8.15 and my daughter was 10.7! It seemed to take forever to heal both times but I found tucks and keeping the area as clean and dry as possible. But if you have an infection of some kind, you may need some topical or something more internal like an antibiotic. I am assuming that after two years you have mentioned this to your doctor???
Wouldn't it be ashame if it was something as easy as prescribing antibotics to help heal all this suffering? Make an appointment today please! Good luck.
