I had plastic surgery just over 7 months ago on my nose (rhinoplasty). Unfortunately, the results of the surgery are not good. My nostrils are lopsided, my nose looks much wider than before just above the nostrils and I now can't breathe through my nose at all. I went back to my plastic surgeon and raised these problems, but his got very defensive and said 'well that's the best I could do'. I consulted an ENT specialist about my breathing problems and he said I'll need to get septoplasty as I have a severe deviated septum. When I asked him if it could have been caused by or should have been diagnosed by my surgeon when I had my rhinoplasty, he said that could be the case but was hesitant to say anything to get the plastic surgeon in trouble. I believe my plastic surgeon has really stuffed up. I'm so traumatised by the experience-its hard for me to even think about corrective surgery for my breathing for fear something else will go wrong and I don't want people to see my face anymore. How do I prove a personal injury claim for medical negligence?
