I vomited daily for months after my SAH, then for weeks after I had my AVM radiated, and am now vomiting daily after having surgery to deal with a fourth ventricle that had stopped draining. I'm sick of it lol and wondered what insight and wisdom other fellow sufferers can provide. My husband is convinced it's because of damage to and pressure on the cochlear-vestibular nerve in the original incident, so happy to hear others' views...
