My feet feel uncomfortable and slightly tingly when i am lying down, which makes it hard to sleep. it's better when i wrap my ankles tightly but i don't know why?

Restless Leg Syndrom: Perhaps you're describing Restless Leg Syndrome (http://www.mayoclinic.org/diseases-conditions/restless-legs-syndrome/basics/definition/con-20031101). If you have diabetes, you could be describing diabetic neuropathy (http://www.mayoclinic.org/diseases-conditions/diabetic-neuropathy/basics/definition/con-20033336) although it takes years to develop as result of poor control. Go see your FamilyDoc.
