Hello, I am having slight pain (feeling a bit discomfort) on the right side of my chest (below shoulder onwards) for the past couple of days. I noticed today that the veins on the right side of my chest are thick, much greener in colour and protruding when compared to the veins on the left side of my chest. Also, I was diagnosed with Hernia on the right side of the pelvic area for quite some time back. I would like to know why are the characteristics of the veins different on both sides of the chest (veins on the shoulder area and below onwards).
