Has changed sleeping habits, sleep day and awake all night. His body aches in legs and stays extremely cold. Anemic and has begun to experience difficulty getting in and out of shower/tub on his own. He has lost 12 pounds in the last 6 months. Continues to see primary care physician, however I think he needs to see a geriatric doctor to get a complete work-up. Recently diagnosed urinary tract infection and sinus infection.
