My husband is 52, 6 1, weighs close to 400 lbs. His knees are causing him severe pain. He has actually lost abou 50 lbs in 6 months by trying to eat more natural food (Daniel Plan). He also has familial tremors which also csuse anxiety, he took himself off the medication about 2 years ago. He is experiencing anxiety, feeling bad, fear of having a heart attack, hot to cold flashes, lack of taste in food. Is he experiencing high blood pressure, tremor symptoms or what?
