Sorry to hear about your symptoms. The pain in your arm sounds like a
radiculopathyHerniated nucleus pulposus which is a condition of nerve root irritation due to things like herniated discs that cause burning like sensations that radiate from the shoulder down to the arm and hand or in your case shoulders and back also. You need to see a neurologist and neurosurgeon, or at the very least get an MRI of your neck and see your primary doc. I'm not quite sure why you were told you had to live with this, but surgery, physical therapy and anti-inflammatory meds could certainly help. Talk to your docs about getting a referral. An EMG may also be helpful to see which disc or discs are causing the pain. Best of luck.
