I had a 2 level fusion in June of last year. I have a cage, rods and screws at L 3/4 & L 4/5. I've had so many problems since the fusion, but this latest one is unbearable at times. For the last week I've had like a very sharp pain in the right side of my back, and when it comes it stops me in my tracks. All I can do is cry out. I feel it clear down my hip and butte all at the same time. I have an appointment with my surgeon next week, but now it's the weekend, and I don't want someone seeing me that doesn't know my case. Also, this weekend is when my insurance is changed to another one, so I'm trying to wait out the weekend. What can this be? I might mention that it has been below zero a couple of days this week and it seemed like I could feel the cold all the way through my back where the surgery was done. I don't know weather to put ice or heat on it.
