interesting...why is that?

Not sure why, I know a lady who had lumbar spondylosis and her leg was always swollen. And same with a guy who had kidney issues. My guess is the kidney issues causes imbalance in salt leading to excess water retention and the gravity is doing the rest. But that's just a guess.
PS : I am not a medicine guy.

What do you think was responsible for the swollen legs in the person with lumbar spondylosis?

Maybe the poor circulation ??? I am just shooting blind at this point.

Will get into the answers this weekend.

We don't have much to go on but I am thinking that the person with spondylosis probably has another condition which is responsible for the ankle swelling.
