I also bruise really easily on my legs, and they are very dark bruises too. Very light bumps that still result in a lot of pain because of the RSD but shouldn't physically cause a bruise do every time. And I also get bruises that I don't know where they came from. At any point you can look at my legs and see them covered with bruises- you'd think I was in some high contact sport or something. I think it's definitely a symptom of RSD.
