    NOTE: For the first 7-14 days, some residual soreness of the extensor muscles may occur due to the lack of direct stimulation during every day activities. This is a normal occurrence, and not to be mistaken for the pain caused by your injury.  Residual soreness will disappear as you increase the strength of the extensor/abductor muscles groups.
