Did you massage the scar ever? Sometimes the scar can stay sort of raised and tight and tender and giving it a quick massage every day helps the area calm down (all those broken and sewn nerves can be a bit "jangly" at first). Try massaging it with lubricant or oil (no oil if you use condoms though!) for a week or two and see if it helps, if not get thee to a gyn for a second opinion.

Hang in there, these things DO resolve with time/minimal treatment in almost every case, but they can take a while. Finding TIME to "warm up" properly can be a problem for many! Best of luck.
