Subarachnoid space is a fluid filled space which is present all around the spinal cord throughout its length. When a small disc bulge is present it first presses on the subarachnoid space and if it increases further, there is a possibility that it will compress the cord. So in your case it is not compressing the cord. There may be orthopedic problem in neck-shoulder region which is causing your symptoms.
Good luck.
