1 year post-op my abdomen is bloated. How can I get the swelling to decrease? Do I have fluid retention or third spacing?

I had one treatment of cool sculpting done one year ago on my upper and lower abdomen. The doctor used the large applicator. I saw minimal results after six months. After nine months my upper and lower abdomen became bloated and swollen. One year later, my stomach has swelling and bloated. I was not told to wear a compression garment after the procedure. Could I be experiencing fluid retention or third spacing?
