Incision pain 3 months post-op, is this normal?

Thank you for sharing your question and I am sorry to hear of your persistent pain. After three months your incision discomfort should have resolved and I would see your surgeon for an in-person evaluation.  With an examination the cause can be diagnosied - nerve issue, musculoskeletal, mondor's, suture - and treatment recommendation.  Hope this helps.

Incisional pain is uncommon 3 months after breast augmentation surgery. There could be a retained suture to remove or simply scar adherence which could be treated  with massage. Please see your plastic surgeon for an examination diagnosis and recommended treatment.
