If it weren't for the weight loss & bluish bruises on your ankles i'd think allergy, but bruises & weight loss could be alot more serious.

I suggest that you, make a note of when this first started (or you noticed it) for each symptom, what you weighed (roughly) before, any dietary changes (any, at all!!) any changes to bowel movements, urine colour etc) any other symptoms (headaches, hair loss, nausea, sleep patterns vomitting, etc - here i'm just thinking of things a dr might ask not suggesting or implying anything, ok?!)

then go to the dr or to an er!

Good luck.
