So like usually I can't see them at all but I woke up today and I could see like ALL of the veins in my hands and wrists and like halfway up my arms. I've never been able to see them before so it sort of freaked me out a bit. Anyone know why this is happening? Thanks :)
Increased blood flow can cause veins to be more visable. Could be a medicine you took, poor circulation to one area while you were sleeping, temperature, etc.
maybe because your blood flow has rised.
