A fever is your body's way of telling you that something is wrong. It is the antibodies multiplying to fight the infection or virus. Dr. Andrew Scott is a Chiropractor in Vaughan, Ontario Canada who recommends that taking medication to lower a fever may not help. A fever encourages one to rest, which is the best way to fight sickness. Medication may make one feel better, but that may cause one to resume activity instead of resting.
