My husband has a condition which has resulted in very swollen and painful feet. They are now waking him at night. He elevates them on a pillow with a soft cloth, but it isn't helping now. He does not have diabetes, but when I research his problem, diabetic suggestions come up so it must be a similar problem. I would welcome suggestions from others. Thank you.
Good luck
Check with his doctor about gouty arthritis, or a spine issue.
Also check for peripheral neuropathy.
As for diabetes, his A1C could be high (pre-diabetes).
He could have a magnesium or electrolyte deficiency.
Do not self-diagnose.
If you have the diagnosis, and need the techniques to help him be comfortable, please let us know.
What does he do during the day? Is he on his feet, at work, or at home? What kind of shoes and socks does he wear?
Another aspect could be swelling from salty foods.
I didn't find anything in your profile to offer any other clues or insights. Perhaps you could help by explaining his daytime activities as well as other medical issues?
