I only have one TC & it is located on my tailbone. I've been to the neurosurgeon. Had lower & upper MRI's done. I had some mild bulging disk in lower back area plus the tarlov cyst. He's adament that the burning pain is not coming from my cyst. He ran bloodwork for autoimmune disorders & inflammatory disorders. They came back negative. Basically, he's done with me. He said for me to go back to the neurologist for more testing. I told him that I have been reading info. on the internet about the cysts and I have a lot of the symptoms. He said not to believe everything you read. Maybe he just doesn't know much about them. All he told me was that if you start messing with it (surgery/aspirate it) you could do more harm than good. I'm on a nerve medicine for the burning. It is not touching it. I'm discouraged.
