2 Months Post-op Right Breast Still Feels Firm and Hasn't Dropped. Normal?

Yes, it may take several months before the implants have completely “settled”. I think the implant displacement exercises (massage) are helpful. I also think that you are correct in concluding that muscle activity may slow the descent of the implant .On the other hand, early encapsulation (abnormal thickening of the scar around the implant) is a possibility.  If this is the case, it  may  improve with the use of medications. It would behoove you to continue close follow up  with your plastic surgeon.

Best wishes.

You are still early in your post operative course. Breast implants tend to start dropping into place after 3 to 4 weeks. They usually will get to their final position in 6 to 12 months. One will usually drop faster than the other, and the shape may go through changes.  Please follow your Board Certified Plastic Surgeon's post op instructions. For example; we like message, but some surgeons will have you wait, or do it in a specific manner. Please let them know your thoughts and concerns.            

After breast augmentation, it can sometimes take 3-6 months for your implants to completely "settle" and for you to see your final result.  I would continue massaging your implants and keep all of your follow up appointments with your board certified plastic surgeon. I hope this helps and wish you the best.
