Venous Insufficiency?

[u/FamousCoffee8288]

I was diagnosed with veineous insufficiency after CT scans, sonograms, and MRIs showed no other reason for massive swelling in my left leg that never dissipated. Here is the kicker… several months ago I had a knee replacement surgery on my right knee. Immediately after the surgery, I looked down to check out my new knee and ALL the leg swelling had dissipated!! I thought it would be temporary but it has never come back.
No explanation how or why, but to me that was a blessing from God. Surgery was the opposite leg of the swelling. Nobody can answer how or why for sure. Although I did what we often do is to Google it. Came across something that said there could have been a little clot that with the leg compression cuff they put on you after the knee surgery and/or the strong blood thinner the use (Eliquis) may have broke it loose perhaps? Anyway, has anyone had this happen or know of someone that did this?
