I can say one thing with absolute surety (as regards myself - 100%)
When I was highly stressed and anxious about my cancer (and subsequent "false alarms") I felt pains, aches, buzzing noises (ears), in my neck and other parts of my body.
It was all stress related - and I am not for one minute saying this is the case for you - if you feel pain - you have pain. But do be aware of the power of the mind.
See your doc for suitable meds.
Good thoughts to you - tony k
