My mother has had problems with severe cramps in her legs for the last 30 years. The cramps are getting much worse. At 76, she perfers to die rather than have these horrible cramps that occur. They are horrible and she cannot stand these any longer. She is a diabetic, has high cholesterol, high blood pressure - takes medicines for all. She screams to the tops of her lungs and goes outside - no matter the temperature - walking, screaming, and praying. She eats raviola for breakfast (!) trying to eat enough postassium daily. She has been to severl doctors to no avail. I feel she has peripheral vascular disease, diabetic neuropathy, or some type of vascular disease and I do not know what kind of tests to ask her doctor to do about it. She stays cold a lot and says she has no feeling but numbness in her feet much of the time. Which tests should she have? She is afraid ALL the time of getting these painful cramps; we can t go out to eat, to the movies, nothing ... she lives in fear of the painful cramps. I am 53 and getting them as well upon occasion and when I get one, it is terrible to get out. Should she have any of the following tests? 1)Peripheral Vascular Disease Test, 2)Angiography and Doppler Studies, 3) Idiopathic Test, or 4) Hypocalcaemia, 5) a venous study of her legs with ultrasound ... What tests would you recommend?
