I have this tiny cut towards the inner corner of my eye that won't heal. Did something go wrong during my surgery?

I had gotten blepharoplasty done two years ago with my savings right before college to fix my monolids. Everything healed up nicely and I went to my plastic surgeon multiple times to check my eyes' progress. It's been two years and I assumed that everything would be healed by now but now there's a tiny cut on the inner corner of my left eye that won't heal. It keeps reopening and it stings whenever I blink and it scabs over and falls off constantly. Did something go wrong? Did I do this?
