Hello~I think you have some misaligned vertebra in your neck and upper back, you could also have Thoracic Outlet Syndrome. All these can cause the symptoms you are having. The chiropractor should be able to help all of them however, he/she will take an x-ray to determine where the problem is and then adjust accordingly. I experience my first three fingers going numb or tingly when I sleep at times, the chiro says it is Thoracic Outlet Syndrome (TOS), nothing serious, but very annoying. It is nerves being impinged in the scapular region, this in turn causes the numbness and tingling, adjustments, as I said, do help.
