Could I have diabetes?

You wont know until you get tested but with the tingling arms and legs and blurry vision it will be advanced diabetes as these are symptoms a diabetic gets if they have had diabetes for a long time and not had medication to control it and the body has been affected. I think it is something else because if you had these symptoms with diabetes you would be in a bad way and I think you are only having mild versions of these symptoms. I am a diabetic. Good Luck
