I had a closed rhinoplasty with L shape silicone implant & nose tip reduction 5 months ago. It was healing well until I started having mild nosebleeds from my right nostril from time to time so the surgeon altered my implant into an I shape. He said there weren't any signs of infections & that I simply had slow healing. Are there any other possible reasons as to why my nose is not healing properly and why there are these seemingly spontaneous occasional mild nosebleeds from my right nostril?
