My friend had this issue. After Dr appointment it was discovered she had fluid around her heart despite taking water tablets. Her salt intake had to be drastically reduced.. Also her daily fluid had to be reduced and counted. Please see your dr or see a cardiologist.

There can be many medical reasons for leg swelling. These should be considered and not assume it is fibromyalgia by default.
However, after being checked out to eliminate any serious illness, mine turned out to be a rare reaction to a medication.

Margi I used to. In fact my whole body was filled with fluid weight.
It was the med I was on. When I got off of it I dropped 15 LBs right off.
The rest came off slowly. It had gotten so bad I could barely hobble.
Hope you get to the bottom of it.

Try stay away from salt. Please have checked cuz could be heart

Not sure you drink sodas or not but wow that will do it. I usually only drink water but when I drink a sprite I retain so much fluid but it’s usually in the gut! After a few days I’m back to myself.
