Skin puckering 2 years after arm lift surgery (photos)

I went back to have a breast lift, no implants and an arm lift. I was told that it would take up to two years for my arms to completely heal, the puckering is still there. My right arm feels a little different than the other. There is also a tightening around my arm, the bicep area. It doesn't matter what kind of light activity I do, such as extending my arm out to hold on the the steering wheel. What could be the be the cause of this, after two years? What can be done to correct this? No weight gain.
