pseudotumor cerebri
"I developed a pseudo tumor over the course of a weekend. My intracranial hypertension onset was so fast because it was brought on by taking an extended round of tetracycline for a persistent sinus infection. My dosage of Diamox had been 1000mg/day but it was flushing my antidepressant out of my system too fast so it was lowered to 500mg/day. The tingling went down, too. I still can't drink carbonated drinks, but that's better for my weight loss anyway. "
