NoSome other information: I have been having digestive (colon) problems. Could it be related?
Skin is thin. Dark veins underneath will be seen (your wrists for example). I notice veins that I did not notice other days only because I take the time to look for them. The days after I do not see them because I barely put any notice to them. Real concerns would be rashes, infections, red bumps, swelling, and irritation....as in something is visibly not correct. I highly doubt there is anything to be concerned about.
