Thank you for asking your query.

I have gone through the description of your medical problem a couple of times. The sharp pain,tingling sensation, the association with neck movement and most importantly the weakness - all point towards involvement of nerves. Rather than a pain of muscular or bone origin this pain could be caused by the compression of irritation of nerves in the cervical region (neck region) when it comes out through the vertebrae or at a nerve group in the shoulder.

This explains the wider distribution of pain - like pain in the back, chest, arms etc. The nerves which comes out from the neck spinal cord travels to all these places. And when the corresponding nerve is compressed you feel pain in that region, not in neck.

I would recommend you the following.

1.An over the counter pain killer for pain
2.Avoid sudden neck movements
3.Avoid straining neck, lifting weight over the head using the arms.
4.Make sure your neck is properly rested while sleep.

I strongly recommend you to meet a Physician without any delay. Hope you would understand my conclusions are based on the information provided by you. A complete physical examination is needed to come to a solid conclusion. And since there is some weakness it better to get it check without further delay.

Hope this helps.
Thank you
