I am in desperate need for some help. My Son has been in the hospital for over 15 days. Really sick he has super high blood pressure with vision disturbances, has lost lot a wieght, is dizzy and doctors can not find the answer. They have done all kinds of test, thyroid, liver, kidneys and they are just about to perform some heart test. Could this be a heart problem? Are they misssing something? As time passes he is just worse and worse what else could cause those symptomss..? He was always so healthy...The only palce he ever worked as was an old mine.
