I had those start on my right calf, then they went to my left calf, then the whole leg, then the other leg, then my back then my stomach, then my arms - a week later they started getting itchy and a little raised! The ONLY thing I could think of was some kind of dermatitis and it started when I began taking the brown flaxseed softgels! Prior to that I had taken the golden ones. I stopped the flaxseed and in about a week all was better. If it starts to spread think back to what you were doing new!
(When I first started getting them they looked like petechaei or something and scared me! I had a BP doctor appointment and asked about them at that time, he just said, "Those are nothing")
