pseudotumor cerebri
"I have had IIH since June of 2014 but was diagnosed "officially" with IIH in May 2014 after my first LP had an opening pressure of 45. I tried Diamox the first time but it made me so tired I couldn't handle it and then I went into spontaneous remission or at least my pulsatile tinnitus went away and I didn't need to keep taking it. I relapsed about a week ago and had an opening pressure of 55 after having extremely loud pulsatile tinnitus for a week. I was put on 1g of Diamox and for the past week the whooshing noise has gotten much, much softer and sometimes I can't even hear it. I take Vitamin C to help with the tingling and have barely noticed it. I'm thankful my body is responding well this time but it's different for everybody."
