I have a lot of pain after otoplasty. Is this normal?

If the pain goes away after you take off your band, maybe it is too tight and a somewhat looser band that still supports your ears would suffice.  Ask your surgeon for input.

Pain is part of the normal post-operative process of an otoplasty. Just to be on the safe side, you should, however, have your ears examined by your surgeon to rule out the possibility of an infection.

Three possibilities. 1- Normal post operative pain  2 - Headband too tight   3 - Hematoma (bleeding under the skinYou need to see your surgeon for a correct diagnosis and recommendation. And I would not wait if you are having that much discomfort this long after surgery.
