KS can happen when you are dehydrated.
It can start as a dull ach in the back/waist section (or a bit lower)
Sometimes the pain can be very VERY INTENCE. Heating pad MAY help.
DRINK pleanty of Water or other liquids ( NOT SODA or Alchole, or coffee) as they dehydrate. There are also certain foods to avoid go to :
