Hi, Today I was in Math class and I looked at the palm of my hand and my thumb pad had turned Blue, I do have a lot of visible veins on my thumb pad. I was not immediately alarmed as I thought I had simply smudged a Blue Highlighter in my workbook, However I went to the bathroom and washed my hands and they were still blue. I came back and showed my teacher and she shrugged it off. It has happened numerous times in the past. I am only Fourteen so I am not sure if it is a serious condition of if I shall not worry.
