My skin has not retracted post MBR and I feel burning sensation on my right chest, what could be the cause? (Photos)

I had male breast reduction 3 years ago, where the gland was removed on both sides along with liposuction, I some times have burniing like sensation on my right side of the chest, I don't know if I have accumulated seroma over the years or I have Laxed skin, please recommend a treatment. I also workout consistently and have a healthy diet, I have also kept my with consistent even prior to my surgery 3 years ago. Thank you
