Last Thursday I had a Lumbar Puncture done. After needle was taking out had experience the worst pain in my life. It was like someone took a hammer to my spine. The doctor said he must have hit a nerve. On Sunday I woke up with instense pain in my tailbone. The pain is still there along with what feels like bad nerve pain in my tailbone that runs down the back of my legs. It hits about every 5 minutes. Takes my breath away. I can't do anything. Is this something that will go away?
