I searched for the right place to put this comment, and I think that this Thread is 'it'. I want to add one more thing that can cause "swollen feet, ankles, lower legs". The culprit is a chemical in canned foods. The cans now have an epoxy lining. BPA. I usually stick with fresh fruits and vegetables, meat, fish, healthy fats, and some starch,...and I like to prepare it myself. But somehow lately, I got "off my game" and threw in some canned foods. Eating canned foods is very bad for the kidneys, and feeble kidneys give you swollen feet, ankles, and legs. Nephritis. So, here's what I did to myself...some canned milk instead of fresh, some canned chop suey instead of making it myself, some "organic" soup from a square aluminum and cardboard carton instead of making it myself, some corned beef (high salt) instead of fresh beef, and a few bites of Spam (yes, Spam. I can't believe I did this to myself). Now, this wasn't all in just a few days. It was mixed in with mostly fresh, healthy food, and over a peroid of about three weeks. But it all caught up with me two days ago. The dreaded big, heavy, swollen foot-ankle-leg syndrome returned,...and some actual pain.
I immediately started taking my kidney herbs (marshmallow root, gravel root, hydrangea root), drinking lots of water, and eating raw, sweet, fruit. I'm so glad that I have pineapple, kiwi, mango, and apples. I've never used compression leggings, and I don't want them. I want to get well!! So, realizing that I had probably "done this to myself", I Googled, and sure enough, there are others who also believe that eating canned food is a one-way ticket to kidney failure. I've checked my leg just now this morning, and it has gone down. I still have swelling, but no pain. And I hope to keep going in the right direction. I offer this link regarding the danger of eating canned foods. It is but one of many.
"Avoiding canned goods is still your best bet to keep BPA out of your diet. Stick with fresh produce and buy products in cartons and glass jars instead. For the latter, discard any food stuck to the underside of the lid—it was probably manufactured with BPA."
