8 Weeks Post Lift Incision Not Healing?

Hi At 8 weeks things are looking good for me EXCEPT a nasty incision that does not want to heal. On the right side (hairline), has a scab that is as long as the incision (about three inches) and is about a quarter inch wide. Been this way for about 4 weeks. PS thinks it's a granuloma and put me on antibiotics because the oozing looked somewhat suspicious. Exams are very painful. Please advise on short and long term treatment from your perspective. Happy with doc, would like some other input.
