I would say diabetes because when you're diabetic you have an elevated amount of glucose. Which causes the narrowing of blood vessels and stiffening in arteries and a decrease in the function of red blood cells. which would mean that white blood cells don't do their job, and fight infection. so with all of this, blood and oxygen flow to the wound are decreased. So the wound can not receive proper attention from the body because it doesn't have enough nutrients or oxygen to heal.
A strain is a twist, pull, and/or tear of a muscle and/or tendon. It usually results in being removed from the activity and possibly placed in the nurse's office. Hope that helped.
