Can breast implant cause costochondritis? I went form A cup to a D cup, can going smaller relief my pain? (photos)

Thank you for your question.  Breast implants themselves do not cause costochondritis, though surgery initially to place them may.  It appears that you did well for a year before your symptoms developed and I would hazard something else may have caused your discomfort, such as a trauma/accident or exercise routine.  Speak to your plastic surgeon and ask for an in-person evaluation to ensure your implants are not the cause.  Hope this helps.

I've not heard of costochondritis from breast implants. Implant movement is common with unders, and that's one of the drawbacks of doing unders. I use a dual plane technique which releases the pec muscle more and decreases animation. Your implants are not overly large, even though you are petite, and are unlikely to be causing symptoms.

Thank you for your question.  I don't think the implants caused the costochondritis, but if you went from an A cup to a D and the implants are under the muscle, it can certainly add to the discomfort.  If you don't like the breasts moving when you flex your muscles, then the best option is to switch to silicone implants above the muscle.  You should talk to your PS and see if this is a feasible option for you.
