What Causes Shooting Pain In The Shoulders Radiating To The Neck?

Good Day, this past Friday night while driving, I experienced pain shooting from my shoulder blades and middle of my back up my neck to the base of my skull, got a extremely bad headache, migraine immediately, nauseous, blurred and double vision. Also a loss of balance when walking or turning my head when i stopped the vehicle. I was taken to the health centre in my area and they did blood work and an ekg on me, administered a shot of tordol/gravol for the pain and kept me in overnight for observation. My headache was rated at an 8 out of 10. The next morning nothing had changed so they started an iv of nacl and a pkg of massax (migraine pain killer)? And also a shot of morphine for the pain. over the day the pain slowly subsided, but they had to discharge me due to a lack of staffing. I still have a bit of a headache and upset stomach and the pain at the base of my skull. My doctor told me that i Just had a super migraine? is there a possibility that i have had a tia stroke? I have been to a back specialist that sent me in for a mri on my neck 6 months prior to this to address my in balance problem and he recommended me to ask my family doctor to get me into see a neurologist or surgeon due to narrowing of the spinal column. My family doctor said there was no need.? Should i be getting a second opinion due to this issue? Thanks for your time
