A Hi Fiona, I see two questions here: 1. What is the best way to address your pixie ear and 2. What is causing your persistent discomfort.
Pixie ears can be addressed with either a minor treatment, or repeating the lift, depending on your exam. I would recommend an additional consultation to evaluate your ear, or you can post a picture to give more feedback.
Persistent discomfort lasting 18 months is uncommon. Muscle relaxers may help, and sometimes physical therapy to work out the soreness. If your primary surgeon does not address those concerns, I would recommend an additional opinion. Best of luck to you.
