Prior to the procedure I would have on and off pain up to a level of 4 to 5 (MRI indicated moderate to severer arthritis in lumbar region). I've been living with it for 18-24 months. I had the temporary nerve block to see if RFA might work for me and for a full day I had 100% relief. That gave me a lot of confidence. But after the RFA (4 levels on left side) I am having pain spikes. I use an ice pack when I feel it coming on and that seems to help. During these spikes the pain hits severe levels (pain level of 8 to 9) although they only last for about 20-30 mins. This happens 2-3 times per day. What bothers me the most is this is the 5th day after the procedure and I'm still having it (it was very bad today). Everything else I read said you might have some added pain for 24-48 hours. Has anyone else had pain spikes 5 days or more after an RFA?
