Hey josephina,
Ah don’t worry too much, from what I understand from all the research I’ve done is that it can take up to a year for your breasts to fully heal after op, and you’ve had implants under the muscle and from what you’re telling me, I think you may be putting too much pressure on your pectoral muscles too soon. Call your nurse honey and get some advice. Your breasts have been under a massive change from op and it will take time for your muscles to recover. Seek advice honey and try not to worry or put too much strain on your muscles. Hope this helps, all the best honey xxx
