I agree with Leesa!

Surgery is going to be in your near future. The cord is generally 11mm you have a 60% cord compression at one location with several others right behind it. I did the same as you and held out as long as I could. The radiculopathy at the levels you have it are painful, but be very glad it isn't at c6-7 or you would think about performing the surgery yourself I had the pleasure of knowing them as well as you do at as many areas. You could lose function of the limb on a complete radiculopathy, but that is secondary to the function of everything from the neck down should your cord get any further compressed. There are people paralyzed with that amount of compression! Hate to bring bad news and again I am not a doctor but I have the T-shirt
