Had Otoplasty About Two Months Ago and my Left Ear Rebounded Way Too Much?

You have developed recurrence of the prominence of the ear, which can occur for a number of reasons.  You will likely require a return to the operating room to correct the deformity.  It is not uncommon to have some abnormal sensations after the otoplasty procedure.  Hopefully the sensations will improve when the revision is performed.

This sounds like the sutures holding the ear cartilage back have become partially loosened, thus having some positional relapse of that ear. When you see your surgeon in a few days, this can be fixed by replacement of the loose sutures to get a better match to the opposite ear otoplasty result.
