I have a painful stiffened neck ( sudden onset ) while i was getting up from bed this morning ? i can't move my neck until now. any advice !

Warm shower: A crick in the neck is due to muscle spasm, often, from sleeping in an awkward position, or due to type of pillows/mattress. Also could be due to overuse of the neck the day before. Try heat, tylenol (acetaminophen) and/or ibuprofen. Gentle stretching and massage, if possible. If it's not any better in a few hours, see your doctor. If you have fever, numbness or tingling, or severe pain, go to the ER.
