Do you feel headaches stiffness or neck pain when you wake up?

Sometimes when you wake up, your neck hurts terribly. This can cause numbness in the legs and arms, or sciatica. Backache and head pain are also common after a restless night. But that’s not all, you feel irritated and tired because of the neck pain you feel when you wake up.How can this be explained? Many people think it is a mattress problem. This is not wrong, but it is not necessarily true either.
