Thanks for asking me to respond. From your symptoms, it seems to me that you might have stained your neck. You need to see your nearest ortho surgeon for a checkup. He will prescribe you pain meds and muscle relaxants that will help relieve your pain. I cannot prescribe meds here as practo didn't permit me to. Do avoid using a large pillow while sleeping in order to further stress your neck. Once pain has reduced visit a local physio who can help you with exercises to strengthen the neck muscles so that you don't get pain in the future. Good luck.
