Hi- Suddenly my body. all of it is full of green veins which have appeared 2 days ago. I am 30 years old, fair skin an obese. I was on a proteins diet for 2 weeks, only eating proteins chocolate bars ( with 0 carbs and very low fat), and last week, I was only drinking 500 ml of water per day with no reason, but thinking of my last week, this is what I can remember: Not drinking enough water. Could this be a reason why these veins have appeared? I am afraid there is a problem with my heart which leads to these veins appearing suddenly ( or at least I just noticed them). Please could you help me? Thanks a lot.
