Hi. I'm a T1 Diabetic with foot drop in my right foot. I also have kidney disease. Recently, I started smoking again, and now my foot is in agonizing pain and it's swelling up like crazy. I wasn't too worried, because usually BOTH feet retain fluid when my kidneys are on the fritz, but the pain is getting worse and worse. Ironically, my blood sugar has been dangerously low, as opposed to its usual highs. Is there any connection?
