I woke up a week and three days ago, and noticed that there was a massive bruise on my calf. The bruise was all kinds of different colors. There was a hard lump in the middle of the bruise, and the middle of the bruise where the lump was a yellow color. Around the lump was a circle that was a purple and black color. Around the purple and black circle was a blue and brown color. Over the next few days the blue color started spreading down my leg. It has been over a week now, and the bruise isn't getting any better. I do not think it is getting worse, but it isn't getting better. It doesn't hurt unless somebody touches it or it bumps against something. I would like it to get better though because I cannot wear skirts, dresses, shorts, etc. because the bruise looks so awful. I have no idea how I ended up with that bruise. I would think I would remember doing something to cause that, but I have no idea. I didn't fall, run into anything, or hurt myself at all...it just appeared one day when I woke up. What causes that, and how can it get better?
