Vigorously massaging breast after silicone BA and was squeezing downward, heard and felt a pop. Should I be worried?

Implant massage after breast augmentation may be recommended by your plastic surgeon. This can help breast implants relax into the correct position as instructed by your plastic surgeon and can also help the scar tissue around the implant stay softer, longer.Hearing and feeling a pop while performing these massages is typically a band of scar tissue or possibly a suture releasing when it is holding things too firmly.  I doubt it was injury to your implant, but contact your plastic surgeon to make sure both you and she/he are comfortable that everything is OK.

It is difficult to say you should be examined by your plastic surgeon to determine what happened. Best of luck.

Typically this would be from a small capsular
(not implant) rupture and in fact, in the past surgeons would purposely do this
for tight pockets associated with capsular contracture. This was called a
“closed capsulotomy” but is no longer done due to increase risk of implant
rupture. If you wish to be sure there is nothing wrong an ultrasound exam is
probably the easiest and least expensive way to find out. Consult with your
plastic surgeon to see if this is recommended.

If your implant is now in a better position, and the breast is softer, you have likely achieved what your surgeon wanted you to! It's very unlikely that you ruptured your implant by doing displacement exercizes. Make sure you go to your follow-up appointments.

WIthout knowing exactly what you surgeon did, it might be difficult to say. It could have been scar tissue your broke up or even suture rupture. Always best to review with your surgeon.

You really need to be examined by your plastic surgeon to determine what happened with the vigorous massage.  Could be any of the reasons you already stated but it does take much force to rupture a silicone implant.

Thank you for your question.  The most likely explanation for the pop is that you were forming a capsular membrane which you popped or broke during your vigorous massage.  The result sounds as though it improved the feel of your implant.I do suggest you see her plastic surgeon for visit and and opinion.  As long as you have had not had undue swelling or bruising which could indicate a bleed you should be fine.
