Minor pectoral muscle extremely hyperactive since surgery 10 years ago. Suggestions to resolve this? (Photos)

I am a 29 female, I received my first breast augmentation at 21 and the procedure did not go well. My minor pectoral muscle became extremely hyperactive it pulled on my shoulder and implant. I received my second surgery that went great 3 months ago to put the implant over the muscle to see if it will help the pain. It alleviated some pain but that muscle is still very tight and extremely hyperactive. Meaning when you press on that muscle it will clench reflex and clench. At this point I am lost.
