Thank you for this very pertinent question. Obviously, an in person exam with the ability to palpate both breasts and ask multiple questions would increase the ability of any of your online plastic surgeons to give you an accurate diagnosis of what could be causing this discomfort. That being said, five uneventful years with no discernible breast problems followed by recent repetitive problems in your right breast secondary to specific movements would indicate something has changed, and more often than not, this is scar tissue. This scar tissue usually occurs circumferentially around a breast implant and is known as a capsular contracture. Since you cannot discern any difference in the firmness of your two breasts, and if my assumption of this being early capsular contracture is correct, then this is a Baker II, i.e. a plastic surgeon can feel the difference but the patient cannot. Assuming all the above is correct, then the most common cause of this early capsular contracture would be going to the dentist, especially for teeth cleaning, without taking antibiotics pre visit. I realize there is some controversy in the plastic surgery community as to whether a dental visit can lead to a capsular contracture. However, since I have seen this over and over in my own patient population, I would be willing to bet that is the cause.If you were my patient with the above history, I would recommend Accolate and ultrasound (the kind physical therapists use for sore muscles) to decrease the chances of you getting a Baker III capsular contracture.I have made multiple assumptions so as to give you at least an idea of what may be going on. You need to contact your personal plastic surgeon, have an in person exam, and follow their advice.
