See your doctor: Injury or blood draw can sometimes result in bruising. A residual discoloration is often due to some hemosidrin deposits in the subcutaneous skin and can give a hue around the injury/blood draw site. However, 90 days is a prolonged amount of time for that to still be present. Medications and diseases can also be related to preventing clots which can lead to prolonged bruising. Get checked!
