I have read thru 6 pages of remedies and haven't seen the one my mother used as a sure cure. Take two large ice cubes and she put them in a pie tin and you have to sit with one big toe on each cube until they completely melt and the cold will not develop. You have to catch it at the first sign that something is coming on, but it does work! I think it has something to do with stimulating the pituitary gland.
