My mom has very swollen feet.

My mom has very swollen feet. They told her to take two diuretic pills, but they don’t seem to help too much. She wears the compression stockings often but she also has neuropathy. Any other suggestions on what to do about the swollen feet she’s also had three procedures done on her veins that were supposed to help, but I don’t see any improvement. Her legs feel better, but why are her feet still swollen? What home remedies/natural things help?Thanks
