I had a sudden stinging and painful sensation in my leg, below my right knee to "my left" on my calve. When i felt the pain, there was a fist-size swollen bruise. It was oddly shaped at first, and had a greenish color. I got scared, thinking it was a busted vein or something worse, so I went to the ER. They just told me it was a hemotoma (spelling??). This happened a week ago. now its the diameter of about 5"-6". the bruising is now a ring and the center is still a little swollen and still has a little sting and pain to it. The color is now turning yellow (which the dr at the ER said it would turn) BUT...its now itching. I don't get it. I have never had a sudden bruise and never had a bruise that itched inside. Any info would help. I don't have a follow-up until next monday (the only time my dr had available time for me). Thank you for your time and any information would help.

p.s. I took pictures from the first day to every other day to today. (if needed)
