The most concerning information in your above post is the abnormal cord signal. If that was reported from an MRI, it typically means permanent damage has already occurred, and you are at high risk of losing more functions, including a risk of paralysis. I'm not a doctor, but I have cervical spondylotic myelopathy and am having a laminectomy and fusion soon to fix it, and I don't have abnormal signal. Note:

" High signal changes seen in the spinal cord of patients with CSM may indicate myelomalacia or permanent spinal cord damage."
