I have reviewed your query and here is my advice.  You must be having compression of nerve at your neck(cervical ) level.You need MRI Cervical spine to look for any compression.compression may be either due to prolapsed disc or soft tissue hypertrophy or any osteophyte or bony spur.On the basis of MRI findings you may be treated conservatively or require operation.
