I've just had the third nosebleed in three days, after blowing my nose. I've also had a chronic cough, but we're having drywall done in the basement and thought maybe it was the dust that was getting upstairs. We haven't turned on the heat because I didn't want the dust going up in the air and register vents. The cough was a dry cough, but now produces some clear mucous. I also was just awakened with the most severe cramping in my left leg that I've ever had. It was mainly in my back thigh, but also down the whole leg. Scared me silly, and I couldn't get up. I don't know if one is related to another...thoughts?
