Had episiotomy 5 yrs ago, I feel like it is very open,when having baths water gets trapped and I find its leaking out after the bath eaven up to 20 minutes later, also when I have looked it looks very open. Should I see the doctor about this?
Is this something a gyno will repair?

Usually episiotomies are stitched back once the baby is born. But, sometimes they're not stitched up or it doesn't heal right for various reasons.

I think you would be wise in visiting your doctor if you're concerned about it. The gyno might not be able to repair it in the office, but I'm sure it's something that can be fixed quite easily if you find the right person to do it.
