Hi, Thanks for writing in. It is important to know the exact location of nerve damage. This will tell us the possible types of nerves affected and if the autonomic nervous system in the spinal cord is dysregulated. This can cause symptoms of intense sweating and feeling chill intermittently. The thermal regulation in our system is managed by a number of structure including the thalamus which is in the brain. Nerve fibers carrying temperature sensation are scattered every where under the skin and this has receptors. Problem in these nerves can make you feel hot at one time and then cold soon after. Please get your problem discussed in detail in view of your nerve damage with MRI scans if available. Please do not worry
