Ruptured My Left Arm Vein While Donating Plasma

Thankfully they noticed early on and applied ice to it to prevent further damage. I used my right arm for donating the remaining 90% of the plasma. I was told it'll heal in a few days to a week, and not much to worry about. Also I was reminded to be more hydrated, and now I regret adding about a teaspoon of salt to 500ml bottled water.
