Muscle pain around silicone implant 4 years post-op - could be a leak or capsular contraction? (Photos)

So I had a boob job about 4 years ago. Then in june I had pneumonia which caused lung pain after. Now I am recovered and the doctor hasn’t found anything on the lungs so I am wondering if it could be a leak or capsular contraction. I had silicone implants done. What I notice is that when I stretch or dont wear a bra they hurt a bit somewhat on the sides of the breast. I had implants placed over the muscle, more when I work out or if I dont wear a bra such as when I wake up in the morning.
