After surgical mishap.. I had nose surgery for a deviated septum after surgery one of the bridges fell back into my nose/mouth

I had to go in the er few days after surgery because plastic bridge fell off stitches to back of nose into roof lining of mouth it was very tramatic & painful a plastic surgeon preformed the surgery made me go into my follow up sooner so he could apologize and remove stitches. My nose looks huge on one nostril and I lost feeling on the tip of nose and feel a bulge. It's still very soar on the upper sides of nose I get a lot of headaches ever since the surgery and have to consistently use nasil sprays cause I get nonstop scabs with a blood clot sometimes on them. I never use to have that and I cant sleep flat now that the healing process is threw I have trouble breathing through my nose still. Also had two stitches left in my nose that they forgot to take out. 12/3/14 was surgery can I sue?
