My ears are tight, painful and itchy several years after an otoplasty. Can I cut my sutures to relieve the tightness?

I had Otoplasty Summer 2011. The cartilage pulled back behind the ears making them look unnatural. It feels very uncomfortable and tight; I sometimes feel shots of pain to the ear and itchiness. I feel ashamed and disappointed and I don’t have the money to pay for another operation to fix the overcorrection, so at this point I’m considering cutting the back of my ear where the sutures were made to release where the ear was pinned at least enough to relieve the tightness and get on with my life.
