The chances are you will feel some progress the next morning. If you switch to a more comfortable pillow, you should feel less pain or stiffness when you wake up. However, it may take a while to minimize neck or shoulder pain significantly. Keep in mind that sleep quality can also affect pain and stiffness you feel in the morning. That is why you should try to stick to optimal sleep patterns, and try to relax when the sleeping time comes. Massages can also be helpful, so consider visiting a parlor or asking your partner to massage you in the evening. If the pain has been present for a while, you should consider visiting a doctor.
