Thank you for you nice question! It seems to be a problem with your body clotting function and the prolonged hemorrhage time; it could be from intrinsic or extrinsic reasons; I don t know if you are taking any drugs for your cerebro-vascular problem (stroke): do your doctor have prescribed you anticoagulant medications ( like K antivitaminics, or newly anti-thrombin or anti Xa-inhibitor drugs); because sometimes for different reasons like food, or drug interactions or because of inappropriate dosing they could exert a greater anticoagulant state expressed with a greater hemorrhagic state; or do you take antithrombotics like ticlopidine because it sometimes causes medullary aplasia and a low platelet count expressed also with hemorrhage tendence; Also different intrinsic hematologic problems could cause that phenomena; Don t forget that you are a diabetic patient and as such your blood vessel are more fragile and prone to exhibit exaggerated traumatic injuries. So to say it short I recommend you immediate blood tests: complete blood counts; INR, aPTT and if your GP exclude any extrinsic causes ( like drug effects) and results a problem with your coagulation system you should consult a hematologist.
