I agree with you. Some spinal pain is unavoidable and you have been tolerating this pain well. There are some patients who have pain that is not tolerable and even some patients who have “poor pain filters” between their body and their brain (the thalamus) and the same pathology in two different patients is perceived differently.
You do sound like you have a significant C4 root compression. The good news about this root is that it is not connected to any significant motor structures (except the diaphragm but this muscle has 5 more root to allow it to work well). Hopefully, a selective nerve root block will reduce the pain and allow this condition to be tolerable.
