pseudotumor cerebri
"I have been on Diamox for many years.  Started out with tunnel vision and then found to have pseudotumor cerebri (which my mom has too).  I have even had lumbar punctures to drain the fluid off my brain as well in the beginning.  This medication has worked wonders.  I did have tingling and numbness in my feet, finger, nose, lips but that eased off by taking Vitamin C or eating oranges, (this was recommended by my doctor and it works).  Now the tingling and numbness are gone.  I don't know what I would have done without this medication.  Now all I do is take the medicine once a day and move on with my life.  Please hang in there and don't get discouraged."
