something sticking out of my hernia wound

[Masonstales]

I just recently had hernia surgery and they said that they stitched my hernia back together and taped my skin back together to let it self heal. I'm now 3 weeks past surgery and I noticed a white tiny string sticking out of my skin in the incision scar. And when I tug on it it seems to still be in me. Do you know what it is?

Probably a stitch has pulled. It should be rejected out eventually but I'd get it checked if it irritates you or the area gets hot/red/leaks anything

It's just an internal stitch. It will soon fall off so don't worry.
