Hi jonlyn,
Honestly that doesn't sound to good. You have alot going on there. Blockage of the foramen resulting in compression of the existing nerve is one thing but anything to do with compression, manipulation or twisting of the spinal cord is a lot more to be concerned about. You dont want to do permit damage too your spinal cord as that can be a game changer. If your surgeon says they need to operate straight away I would take this extremely seriously. I would seek advice of two surgeons because opinions can vary by abit. But if you have to wait to long to see another i would probably take up there advice. How much pain are you in? Have you had any loss in bow movement, feeling in extremities or motor functions? if so it maybe best not to wait as you can do permit damage.
Good luck
