I know this post is a bit old now but here's my story in case you still find it useful...

My DS is 8 months old now and I STILL have pain DTD. I had tearing and an episiotomy but my OB did a very good job stitching me up and it's all healed well. I finally went to see Gyno yesterday and was told after thorough appointment that the ligaments holding my uterus in the right position have becaome slack following the prg and birth and so now my uterus is tilted backwards and DH is prodding the side of me in there and that's why it's painful. Was told to try certain positions when DTD to see if that helps, it may right itself or there are procedures I can have done later if I want to. I'm not saying this is your problem but I too thought it was tender scar tissue and thought it would eventually get better. I put up with it for far too long and I know it can have a big affect on your self-esteem and your relationship. Worth getting it checked out. Having said that, given the timing of this thread, I hope you've got it all sorted by now!!
