My mother is 95. She was in good health, driving and living a normal life, until last May. She has high BP but takes Inderal twice a day to control it. she takes Lyrica for neuropathy. She has a heart valve and takes Coumadin. Then these symptoms started: dehydration rash on back, inside of legs and arms, flushed face low sodium nausea restlessness periodic dizziness very weak bronchitis swollen legs urinary tract infection Twice she has gone to emergency room in last 3 weeks with convulsive shaking, nausea, dehydration, low sodium . She has stayed in hospital several days each time on IV. Dermatologist has given steroid shots for rash in June and July and done biopsy, then told her to go elsewhere because he cannot diagnose. Tonight she has nausea and weakness again. Could this be kidney related? We see GP and cardiologist Monday. What should we ask for? Her sister is 99. do not want to write this off s old age. Thanks-
