Does the muscle recover faster after second breast augmentation in comparison to the first procedure?

I am curious- I had my 2nd BA 4 weeks ago, went to smaller implants and had some lateral internal sutures to make the pocket smaller. They were put out under the muscle originally and again with my 2nd BA. I am curious, when you replace implants under the muscle does the muscle still need to heal after 2nd BA surgery since it was already elevated during the 1st surgery originally? What is the process?I feel pain after driving and wondering if my muscle is sore or still healing? Thank you!
