I had a massage 3 weeks ago. Deep tissue on my back. After that I have sore right side breast implant area. (Photo)

There is always the potential to develop capsular contracture over time.  After 15 years it's strange to develop soreness from a massage.  I'd recommend visiting with your surgeon to examine your breasts.  Ask yourself if you've notices any changes to the softness or contour of your breasts as it's possible you're developing some contacture which could possibly explain your breast soreness.  Best wishes.

It is possible that the massage caused some pulling or strain around the breast capsule.  If you are concerned, I would suggest you have your surgeon examine you to see if there have be any damage or displacement of the implant.  Best wishes, Dr. Lepore.
