Anytime you have a change in sensation that concerns you after having implants. it may be worthwhile to be seen by your surgeon.
Thank you for sharing your question and I am sorry to hear that your breasts are causing you discomfort. Without a full series of photographs or an in-person examination it is difficult to offer you definite advice and seeing your surgeon is the best way to obtain a diagnosis and treatment plan. Best wishes.
Dear sydiav, It is impossible to answer your question without examining you or , at least, seeing your front and side views pictures. It is not clear what do you mean with the word "strain" . Is it capsule contracture ? Is it saggy breasts ? Your best mode of action should be to consult with your surgeon or get 2nd opinion from an experienced board certified plastic surgeon. All the best, Dr Widder
