Research shows that in most cases rest for more than a day does not help and may actually prolong painful conditions. You may need to modify your activities initially within the constraints of your pain but keeping mobile will help your recovery. Changing your position or activity frequently throughout the day will help to prevent and reduce stiffness.
Keep the painful area mobile, yourself active and build up your general activity gradually. Your practitioner will advise you whether rest or maintaining activity is most appropriate for you and your condition.
