Welcome to HealingWell. Do you have diabetes? I'm asking this because you're already testing your blood sugar. I think you need to see your doctor and discuss all this with him/her. Being thirsty and peeing a lot can possibly point to diabetes. Maybe the foot problems are related also, but you won't know this unless you see your doctor and have some lab tests done. Those blood sugar readings are somewhat high if they were taken 5 or 6 hours after eating. Please make an appointment with your doctor soon, ok?
