No i never had "the" headache, but it sounds like a consult couldn't hurt & might help. Have they checked your reflexes? Hyper reflexes can be a symptom of CNS involvement (in addition to severe headache & visual disturbances).
I'm glad you are in hospital getting checked out, it sounds like doc is taking your concerns seriously.
In your shoes, with URQ pain & now naseau, I'd want some blood drawn to check for HELLP syndrome.
Good luck, and please keep us posted as you are able.
