Hi @pedie. Sorry to hear about your vertigo symptoms and your medical team's inability to help much. I have never run across a case where urinary tract infection is a cause of vertigo. Bacterial infections involved in vertigo are cited primarily in cases involving the ears and sometimes in facial or cranial lesions. I suspect that your neurosurgeon's assistant is naturally inclined to look for causes other than the hydrocephalus drain, and I'd want more detailed information about the status of my acoustic neuroma. Your symptoms and treatments thus far strike me as inviting a second opinion from an independent specialist who is willing to explore nervous tissues in your head. Are you in a position to pursue a second opinion?
