So as i was heading out for a surf this past weekend i noticed the water looked more disgusting than usual and smelled like **** with some sort of algae growth that looked like red tide. I ignored this and surfed for a few hours. A few hours later i became extremely sick with a throbbing headache, vomitting and extreme tiredness. The illness has now passed and i feel fine. Could this of been from the water and has anyone had similar experiences?
