Swelling can be normal after breast augmentation, but it could also be a seroma as well. If the fullness subsides over the next several days then it was most likely just swelling and you will need to temporize your activity for a little while to prevent recurrence. If it does not reduce after several days of rest then it could also be a seroma (fluid collection around the implant itself) and you would need to be evaluated by your plastic surgeon.
Sure, the recent push ups and use or overuse of the pectoralis muscle may be causing your pain and swelling. Put ice on it, take some ibuprofen, and rest the muscle. It should resolve in time. Consult your surgeon for advice and guidance.
It is not unusually to experience some soreness and/or swelling after exercising, following breast augmentation. In most cases these symptoms will resolve over time. I would suggest you limit your arm and chest exercises for the first couple of months. If the swelling or soreness persists be sure to let your surgeon know. Best wishes.
It is common to get a variety of aches
and pains and zings and pullings and pushings and funny feelings and
numbness and itching that you can't scratch for at least six months after
surgery. These unusual feelings are response of the body stretching over
time to accommodate new implant.
While you're description sounds quite normal,
the safest thing to do would be to just check in with your plastic surgeon.
Best wishes on a full and complete recovery.
Swelling after surgery could be a late fluid collection or seroma which is more common with the textured devices that you have described, you should see your surgeon for a physical exam and potentially some non surgical drainage options
It is possible that you are having some muscle spasm creating the appearance of swelling or fullness in the upper pole of your breast after doing push-ups. With shaped gel implants, like the 410, I usually suggest waiting at least six months prior to starting strenuous chest exercises (bench press, flys, push-ups, etc).
Without any pictures or an in-person examination it is difficult to answer you. You need to be examined in person. Please see your PS or another PS in your area.
