After two months of headaches, double vision and back pain, all MRIs came back clear. Except one that showed the Dura layer of my brain is inflamed. I had a Lumbar puncture test to get fluid to test for why this is happening. However, after three attempts, they could not extract any fluid. Will be seeing a neurologist to examine a possible leak. But I travel for work and don't know if traveling one the next two weeks is wise. Vehicle and Flying.
