I'm so sorry to hear about what you're going through. I know what constant pain and sleeplessness can do to you. Are you taking any meds specifically for nerve pain? Is your physio an osteopath? You might want to talk to him/her about alternative pain methods like acupuncture or reiki. Also, there are various approaches to pain self-management like the Egoscue and Feldenkrais methods.
Time to see another Doctor.
Im sorry your experiencing so many symptoms maybe get a second opinion on what can be done for your neck , I have similar symptoms to you and I fully empathise I keep going to my gp complaining that I can't cope with the pain I know that in for a fight I believe I need surgery iam scared but not as scared as the pain and other problems hurt take care .
I think your right Kalvin
It's time to kick on and get a Dr that knows how to deal with this type of injury
Back to wearing my collar I'm not happy with the way this is going
