--depending on what direction the propulsus is spreading from the disc, might account for more symptoms than just the upper limb ones. If it is affecting just nerve roots off to the side, then hand/arm symptoms would be the rule, but if it's affecting the cord itself, you might have symptoms in any part of the body below that level of the neck.
Still, given what you're describing, sounds more like you have some infectious or autoimmune problem going on. You definitely need more extensive testing, preferably at a tertiary center/teaching hospital, and using the Liza Jane spreadsheets at
www.lizajane.org might be a good place to start to suggest tests to doctors and to track results over time.
