Ask a Neurologist and Get an Answer ASAP
Hello and thank you for your question.
The ringing in your ear is called tinnitus. There are manes causes of tinnitus, like inner ear disorder and that can be one reason that when you get head nodding also called a tic it may aggravate more.
Anxiety can cause both head tic and tinnitus.
Regarding the second symptoms, the tingling and numbness associated with pain in hands can be due to nerve compression in your neck. This is the reason that you feel no symptoms in certain positions as in this positions the compression of the nerve is not the severe.
You clearly have muscle tension in your neck which is causing this compression of the nerve and electric shock type headache where irritation of C2 NERVE can lead to such headaches.
I would suggest to see an ENT doctor and a neurologist who can order MRI of your neck to evaluate further.
A neurologist can also evaluate if you have a Essential tremor which is causing such head rocking. Anxiety can also exhibit such head nodding and tinnitus.
Medicaiton like lyrica can help with such pain and tingling.
Please get back to me if you have any further questions. Thank you.
Yes it can be due to nerve compression in your cervical spine.

yes as nerve controls the muscle activity and if nerve is compressed muscles get weak leading to muscle weakness.
