Black eye

I woke up last Saturday with a black eye. Until now, I can't recall that I have hit my eye. I suspected My unfractioned heparin as the culprit. I asked my obstetrician whether I can reduced the dosage of my heparin or not. She changed my medicine to low molecular weight heparin. Clexane needle is quite coarse. It is painful when injected. I feel the radiating pain on the injection site, wahaha up to my pockets. Ouch... expensive.

Is heparin really the culprit?  If i am very prone to bleeding and hemorrhage, why my bruise is on my upper eye lid only? I don't have any other bruise in my body except the one on my right knee. I bumped into something... I forgot where but there is an evidence of scratch on my skin.  My stool color is ok. 

Blood clots and blood vessel breakage is scary. Is phlebolith considered as blood clot?  My pelvic xray decade ago  revealed a phlebolith. The xray film was missing. But, I remember I asked my rheumatologist why my vein is torn apart. Those heart bypass patients also get graft from their leg vein. Nothing to worry about phlebolith. I am just curious to know whether it has correlation to my antiphospholipid antibody syndrome. I guess there is. But, can it cause veins to tear apart? Or the idea that my veins were torn apart is just a product of my imagination?

So, what caused my black eye?

I miss my immunologist.
