I suggest you get the blood test! I have 2 factors for blood clots Prothrombin and Lupus Anticoagulant I had 5 clots in my lungs.
a few years ago i was suppose 2 get a bleed test done but my insurance wouldnt cover it, & i couldnt afford it. no im not on any meds 4 it. but i always hav bruises on my legs.
Yes, blood not clotting properly causes bruising. Yes, you should go see your physicians and ask for the definitive diagnosis and ask for what treatment they recommend for this condition.
I suggest you see a Vascular MD and until you see your MD sleep with your legs elevated
When you say your blood doesn't clot properly are you on blood thinners and or do you have any factors for clotting?
