Why does my neck feel really strained when i work on my shoulders?

This region is where alot of people hold tension which makes it easier to be affected. It is common for a neck strain to affect the shoulders. First because nerves of the lower neck communicate to the shoulder and second because alot of neck muscles have attachments close to te shoulder. One of the best things to do to help the strain and prevent it in the future is to make sure neck alignment and neck posture is good. Use of neck pillows can help you correct thing and all you have to do is sleep on it.
