I have bright red dots , the size of pin heads, scattered on both legs, upward area of the legs. They do not itch and are not raised or painful....just there. Noticed them tonight as I was getting undressed. Some are very close to each other, others are2 to 4 inches apart.. Some are a little bigger than others. I had Sauerbraten and red cabbage for dinner tonight...could the vinegar or onions have caused this? I would appreciate any help. I doubt I have would have to see a doctor, because they don t bother me, but what do you think?
