I had Radio Frequency Ablation done approximately 5 weeks ago. After dealing with lower back pain (mostly on the lower right) for 4.5 years and trying several other treatments and injections, I was accepted into the pain clinic. After doing two trials of medial branch blocks my specialist was convinced it was the facet joints causing all of my pain. Well I am happy to say it has worked, my pain has dropped by 60%. This is fabulous! But I am left with a different sensation and wondering if it could be linked to the RFA? I get very overheated all over my body, all through the day and the night. My face at times feels like I've got a massive sunburn. It's very uncomfortable. Has anyone ever had these symptoms after having RFA? I feel like I'm loosing my mind!!
