If I were you, I'd be describing this pressure and your response to the lumbar puncture to the Neurologist. There is a condition called Pseudotumor Cerebri (a buildup of cerebro-spinal fluid in the brain), also called Idiopathic Intracranial Hypertension, that has some striking similarities to your description above...and it can lead to vision loss if not treated. Interestingly, this condition has been reported as possibly caused by Lyme Disease, and also theorized to possibly be connected with hypercoagulation.
