 [ Symptoms ] i was vaccinated about a year ago but cough sounds like whooping cough and it has been going on for 2 and a half weeks it started out like a cold but i just cant seem to get better and now i have dark urine and burning when pee and blood in my stool [ Disease ] good for you for noticing this it is important for people with chronic conditions like diabetes to stay on top of any physical changes in their body i suggest you call your primary care provider for an appointment the kind of swelling you describe sounds like fluid retention or  edema  this can be a sign of an underlying medical condition possibly related to your diabetes or something else entirely mild one sided edema of the lower leg is not necessarily cause for alarm in an otherwise healthy person but it would be best to get it checked out wishing you well
