Please help. I am basically on my last leg, so to speak. 2 years back I was having constant headaches, so I went to neurologist who ordered an MRI. In the MRI, she found a Chiari Malformation. A few weeks after, she scheduled me for a lumbar puncture to see why I was having headaches. After the lp, my headaches went away. However, since then, every spring and fall I get blocked Eustachian tubes and problems with my ears and behind my ears down into my neck. Pain and a watery/air sensation happens every so often. Could the lp have made my Chiari Malformation cause me to have this type of sinus issue now? Basically any doctor I have spoken to either thinks I am crazy or just tells me its sinus' and it has nothing to do with the lp. I've basically have come into a depression since. I really need help guys
