See your doctor. I would say see your doctor for an evaluation. It can be as simple as a neck spasm and can be relieved by a nonsteroidal inflammatory agent like ibuprofen. If you have stiffness then it is a spasm.
Depends. There are a lot of potential causes of neck pain. Each potentially has different treatments. Thankfully, most cases respond to simple thinds such as rest, moist heat, and the use of antiinflammatories. If symptoms persist, seeing a professional to determine the cause is a reasonable next step. Thank you for your question.
