Discovered recently that the stitches I had 2 years ago for my third degree tear were permanent rather than dissolvable (the surgeon made a mistake...) and I'll have to have them removed because they're causing me problems (very sharp feeling, feel like thorns sticking into me). I'm so annoyed that they used the wrong stitches (nylon apparently) and cant believe this could have happened. The surgeon whos going to do the op said this is very rare so would be interested to know if this has ever happened to anyone else...
