(edit: what I know about them is that if you are thinking one is coming on, you shoulddrink 3 glasses of water--(mayb ehave some cayenne too-- this suggests dehydration is a big factor(?)
What are the contributing factors, that you are aware of? "Calcium" flashes a red sign, but in what way--all hyperbole aside? My partner thinks my mother might be in iminent danger of one.(Hip replacement, bleeding ulcers, a haital hernia, transfusion, and now recuperating -slowly- from that.)\\
Update-- i hear she has gone outside the last few days! also has taken some B shots --this is a very good sign!
