Butterflythree, I wanted to comment on your husbands leg pain. If his knees are the complaint I doubt that it is potassium, if his muscles ache than it could be his potassium levels. You won't know for sure until labs are drawn. You can ask him to be as specific as he can, maybe even showing you where it hurts. That way when you report it to the Dr you can desribe the pain. Drs often ask people to evaluate their pain a a scale of 1-10. This is common for most medical professional to ask. It gives us an idea of how severe the pain is. 10 is described as the worst pain you could possibly have or imagine, 1-3 is usually discomfort, 4-5 is pretty uncomforable,anywhere from 5-7 is very painful but and only moderately tolerable, 8-9 is quite severe and serious pain. again a 10 is horrific and the person is screaming in agony. It sounds a little kookie to ask that question but it is helpful to the medical staff in evaluating the pain. This scale is used for most complaints of pain so you may hear the Dr ask him to describe and scale it. Hope this helps a little.
