Pulling up a topic generated from an earlier post by JR Babb.
In the post, he/she talks about the appearance of "rusting" on the lower legs. This is a discoloration visible beneath the skin, and it has a yellow-orange-brown characteristic to it. This is evidence that there has been bleeding in those vessels, and the "rusting" is the discoloration that comes from the release of iron from the red blood cells.
Sometimes, this is a function of thrombocytopenia (idiopathic or otherwise). Even people who take a bit too much aspirin can experience that effect. Either way, it is wise to discuss this symptom with your doctor, since it might suggest that there is more bleeding going on than you and he might like. I would also suggest that you consider having a serum ferritin sample done, so you can be certain how much of an iron load you're carrying around. Too much would not be a good thing, since any kind of stroke could lead to what is known as a reperfusion injury to tissues, which could be badly damaged by the sudden re-flow of iron-rich blood after a cardiac or cerebral event.
All the best...Jerry
