8 years Breast Augmentation postop and left breast is swollen after muscle strain - what could this be?

HelloThankYou for the question and so sorry to hear that you are in discomfort.It can be a simple muscle strain which will improve with anti inflammatory and cold compress but I advise you to have an ultrasound scan to check the position and integrity of implants, capsule formation and collection of fluid. Kind regards

Dear mrsmmgriff,
I understand your concern. However, without a proper assessment, it would be difficult to determine what is wrong. It is best that you visit your plastic surgeon for further assessment or ask for a second opinion. Only after a thorough examination, you can get proper recommendations and advice.

What you describe is likely an injury to your muscle from the exercise strain. Rest the area and use ibuprofen if not allergic. If no improvement over the next few days or if symptoms worsen, contact your surgeon or primary care physician for an evaluation.

I think you may well have answered your own question. It's likely that you have caused a little tear in the capsule of the implant while exercising as the capsule is stuck to the underlying/overlying muscle which has bled a little. You can use ice packs and a good support bra with anti-inflammatory medications while things settle down over the next two weeks. If the swelling/hardness remains or worsens after this time then see a plastic surgeon to ensure nothing else is amiss. good luck

You may have torn some scar tissue or capsule in your breast and now have excess fluid. I would suggest seeing a plastic surgeon and getting an ultrasound.

It’s hard to say, but you may have torn scar tissue or capsule during your exercise. If there was bleeding associated with the injury, it could be just fluid around the implant or a capsular contraction starting.
Return to your plastic surgeon for evaluation.
Best wishes,
