Could I still have swelling three years after tummy tuck?

I got a tummy tuck in Feb of 2022 in DR. I also got lips of my sides and muscle repair, bbl. I kept my drain for 30 days because it was still at about 75 cc everyday. Everything healed nicely no infections or issues. I wore my raja for about 6 to 7 months. When I finally stop wearing it I will swell up as soon as I got out of bed. Finally went and had an abdominal ultrasound, I had a very small slither of a fluid pocket that the interventional radiologist say was too small to drain, there was a lot of fluid with my abdominal tissue though. It’s been 3 years and I still swell up badly, no pain just swelling. I have never experienced a flat stomach. My swelling is above my belly button but I can even feel the swelling in my middle back. I don’t know what to do. Is it swelling or did my muscle repair possibly come loose and is there a way to know before having anymore surgery done?
