As a contractor in Iraq for two years I suffered several nosebleeds. The nurse told me to drink more water and take long hot showers to hydrate. I went to Afghanistan having the same nosebleed And a rash on my body.I asked a friend at the water point about the rash. He said be careful of the water because they were putting large volume of chlorine in it. I had a stroke from plaque. could the chemicals in the water cause my problems? ..
