hi... i'm working in the middle east since 2003... for the last few years i've noticed dark bruise like spots on my legs around the shin area. i wear work boots, cross my legs when sitting at a desk at times, but this worries me what could cause this? i'm 5'6, 37yrs old female, I carry my weight very well and weigh 227 pounds. I've lost nearly 100lbs and have kept it off for about a year. I've been taking phentermine for quite a while, but not consistently as I do not need it most of the time. I've been letting my last "prescription" last. A 2 month supply has lasted me nearly 4 months. I still have several weeks worth left. My mother has a history of anemia, my father's family has high blood pressure and diabetes. Myself, I tend to have low blood pressure. If I'm in a cold room, my skin can be at times icy cold to the touch. Recently, I noticed in my thumbs and index fingers when I may be working they "Lock" up. Sometimes my hands tingle.
