I have been having extreme tiredness, dizziness, short of breath etc for months. My DR said that my last labs show kidney slowing and heart something or other. I have a multitude of health issues such as fibromyalgia, chronic fatigue syndrome, severe muscle spasms in my nevk and only have 25 perceny of my intestines left. My question is, what dr should I see next? Im so exhausted that more than not will fall asleep talking to someone, or eating etc. My dr wanted to hydrate me, but can t get a vein. I drink tons of water and urinate just fine. What do you suggest?
