My PCP told me this is one of those "as we age" things. No one likes what comes after that phrase (our skin thins with age). He told me these blood spots are called senile purpura. I told that to a friend who did not like the sound of that. My PCP told me I could call them activity bruises. I get them regularly around my wrists when I bump something. I am not taking any meds that would cause these spots. I currently have one about the size of a dime on my left wrist. As soon as I bump into something, I tell my husband, "That will be a senile purpura soon." Yes, it is there. I am so sorry any of you have lots of these. I have always had thin skin and now you can almost see my blood flowing on my arms so I just ignore them. With all good wishes, @joybringer1.
