First of all, keep in mind that I am unable to diagnose you because I am unable to examine you, this forum is for educational purposes.
The symptoms that you describe are non-specific, but are often seen in patients with pinched nerves caused by disc problems or arthritis in the neck (the fancy term is cervical radiculopathy). This occurs when one of the discs in the neck protrude to compress a bundle of nerves that is exiting the spinal column (or the nerves can be compressed by a osteophyte (in arthritis), a compression fracture or rarely a tumor). You need to have testing before this condition can be diagnosed. I would talk to your hospital about applying for medicaid or other state/goverment assistance to allow you to see doctors and to get testing. You need an MRI of the cervical spine and an EMG of the upper extremity. I would also recommend that you see a neurologist to help interpret your tests and to prescribe the appropriate medications and recommend any additional care that may be needed.
I hope this has been helpful.
