My left eye swells at the bottom, this has gone on for 3yrs now. I was told I need to purge toxins out. Don't know how to do that. I drink 100 ozs of water a day. Sometimes when I drink water my eye swells feels like its shrinking, the inside is very red, immediately after always lasting 3 to 4 days. This can happen with or without water at anytime, I can be anywhere and it just swells up outof the blue. I was out with a friend and we were talking and it just started swelling. I don't want to go out because of this. 3yrs ago in Florida is the first time this happened to me..it sent me to the hospital, my eye was swollen shut, face swollen had red indentions all over my face. Since then it's been swelling. How do you get toxins out of your sytsem? Why does water make it swell sometimes?
