pseudotumor cerebri
"I was just diagnosed with IIH/PTC last week.  My neuro started me on Diamox the same day.  Although I have had tingling in my hands and feet as well as lethargy, the pressure behind my eyes has already started to go down.  My ophthalmologist was very pleased today with the optic nerve scan and said there has been decrease of pressure in both eyes.  A little tingle here or there and a bit of sleepiness is worth saving my vision!  So far, I'm a happy girl!"
