I have a 20 year old female friend who has had many different health problems. Within the last two years she has been diagnosed with kidney stones, anemia, pancreatitis, hypokalemia, mixed connective tissue disease, asthma, raynauds disease, mono, bronchitis, pleurisy, pericarditis, chostochondritis, uti's, kidney infections...She has had a fever for weeks...The drs say her potassium is dangerously low and they've given her multiple IV's with potassium, but it hasn't helped make any improvements. Does anyone know if there is any certain disease/disorder that may cause all of these different problems? Any suggestions would be very helpful. thank you
