I was diagnosed a few more than ago with Arachnoiditis by a neurosurgeon. He sent me back to my family doctor with the comment no injections in your spine. I currently don't have a reason this disease occured. I had no injections or surgeries of the spine. I fell shortly before the symptoms occured. Pain didn't start for about a month. Pain in left hip down back of leg to top of foot. I am nw on gabopentin and increasing every four days. At this point it is better but not sure if this after what you call a flare up. This is new to my family Dr. Today I am having burning and pain in my tailbone area but it is mild. No pain in my leg. Not sure what sites are dependable for information.
