Hi, I was diagnosed with colitis last August. My mother was diagnosed with multiple sclerosis this week. Over the last few months I have been getting terrible itchy thighs. I scratch not hard, and then feel like something is dripping down my thigh. When I then check my leg, I have red spots, and then what looks like a red rash. Within 1 hour I check again it has swollen and dark red with black bruising start. When I ve checked my legs I have a bruise on my left thigh I didn t know about and a few small bruises on my shins. I have no recollection of banging my legs or hurting them in anyway that would cause bruises. My left knee hurts when I walk and has hurt for over a week. Any ideas on what s going on? Thanka
