On BD sometimes it hurts where I had my second degree tear 9 months on. Seems to be getting better all the time though. Guess it could be where the nerves were and they may have been slightly damaged? As well as any scar tissue.
I have same as kbaby - tore badly and was cut for ventouse with my first. Maybe some nerves were cut/damaged and increase blood supply at certain times/hormones do make it worse - hadnt ever thought about it - just thought it was fact of motherhood - how accepting am I??? No problems or tears with 2nd though - but still pain from first!
