question: My husband is 67 y/o. Was hospitalized last week for 3 1/2 days with severe CHF. History of stage 3 renal failure, severe chronic pain, prostate cancer, malignant melanoma. We have been limiting his fluid to 2 liters per day and adhering to a lo-sodium diet. Only changes in medications are he was taken off of Cardizem and metroprolal tartrate was reduced from 150mg/day to 100 mg/day. He has started to take melatonin for sleep aid and using Lidoderm patches in addition to Morphine and Oxycodone for pain. Since yesterday he has developed uncontrolled twitching in both hands and arms. He is dropping things. He says he feels twitching in other parts of his body. (Oops forgot history of hemoragic stroke 7/1/13). Any suggestions? Thank you Tom and Kathy Evans
