I don't know, not really. There just little 1/2 inch lines. Kind of around the big long vein in my arms 2 around where my arm bends and one in my forearm. And now that I keep looking at them I think my veins look bluer lol and now I'm scaring myself. maybe reddish purple. One is for sure more on the purple side.
Never had zits or red blemishes on my upper arms either. But I've also been sweating and detoxing and have my period around the same time I noticed the veins.
edit- was just thinking. Could "Bed Bugs" do this? I think those little suckers are back.
