I went dancing 2 weeks post-op and my breasts are al little sore now-- how will this affect my silicone implants?

Congratulations on your breast augmentation.  From your description it is unlikely that she damaged her implants.  I considered two weeks still in the early recovery phase and would suggest less vigorous activity for another week or two.

In my experience, early after breast implant surgery involving the pectoralis muscle, it's similar to an athlete who tries to get back to training early after a muscle injury. The simple repetitive movement and stretch of the arm aggravates the inflammation of the healing process in the muscle. As long as there is no rapid expansion due to bleeding, you should be fine. Hope that's ehlpful.
