My son has been having severe headache for weeks and he has been having heavy, heavy diahrea for a couple of weeks, and now he is vomiting, looking for a bathroom (I m sure for the diahrea) and is having another severe headache. Please tell me what these are symptoms of. He is a body builder and I am aware that he takes steroids (though I can t find them), insulin, tons of protein powders and more probably. He won t tell the doctor all his symptoms. I need to help him but don t know what to do so please give me some ideas. Thank you. Very concerned mom.....Crystal
