Hello, i have a friend who has been experiencing extreme low blood pressure, he looks dehydrated and sunk in pale skin, a sore throat, he was fine when i saw him not this past Monday but the Monday before that he had trouble getting up he looked weak and looked like he was getting a cold he also seemed yellow in the skin and eyes. Also, I am afraid that he might have some sexually transmitted disease and he is not letting me know, he is a 39 year old 5 11 180lbs male.
