Accidental Heavy Lifting After BA. What Damages Have I Caused? (photo)

Thank you for your question. You definitely want to follow your own
surgeon's post-op activity instructions. This is a general guide I give
to my patients as to the recovery after breast augmentation:Week 1) Discomfort and tightness
level progressively decreases with each day. Swelling decreases a great
deal after one week. Most people return to work in some capacity.Week
2) Unlikely to need any narcotic support except maybe at night.
Swelling and tightness continues to improve compared to week 1Weeks
3-6) May need tylenol or ibuprofen for intermittent discomfort.
Swelling completely resolved. Tightness may continue as the implants
over an additional few months into their final position. As far as activity, here is a safe guide:1) No heavy lifting or strenuous activity for 6 weeks (a gallon of milk as a guide).2) Resume walking at a leisurely pace right after surgery (e.g. 2 mph)3) At 2 weeks, you can walk 2 miles at 2mph4) At 3 weeks, you can walk 3 miles at 3mph5) At 4 weeks, you can walk 4 miles at 4mph6) At 5 weeks, you can jog 5 miles at 5mph7)
At 6 weeks, you can resume all activities, but listen to your body and
use discomfort or tightness as a guide so you don't over do it. So
as far as the little ones, I would recommend having help for basic
needs like lifting into the car seat. You can cuddle with them while
you are sitting down, but you should avoid the tendency to multitask
with one child in your arms while you are busy doing other tasks.I would keep your surgeon informed of the breast changes after lifting, especially if the pain persists.  Your implant should be intact, and it is most likely just a strain on the tissues causing increased discomfort. 

I'm sorry to hear about the concerns you have after breast augmentation surgery. Despite best intentions, online consultants will not be able to provide you with precise/meaningful reassurance. Your plastic surgeon will be your best resource in this regard.

 Having said that,  neither your description of events or photo graphs are concerning. It is very unlikely that the amount of “trauma” that you have experienced would be significant  enough to cause breast implant rupture.

 Again, follow up with your plastic surgeon for the best advice/reassurance.

 Best wishes.

Normal activities will most likely have not long term effects on your breasts.  Just be careful and avoid activities that make the breasts bounce up and down.  Moderation of activities is the key after breast surgery.  It is the repetitive bouncing up and down that you want to avoid.  Also it helps to wear a well fitting bra.
