What is it like to have severe neck pain?

It hurts. I am lucky enough to have never experienced severe neck pain myself but patients tell me it hurts a lot.
It hurts. Well it hurts. You may also have associated headaches as well. You may have limitation in head mobility. You may have muscle spasm also. Sometimes it feels like a vice around the neck.
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.
