You can use the search feature and archives and read about pseudotumor cerebri. Be sure you read the side effects of diamox; most everyone has some. Most are mild and something you have to put up with. Diamox is also used to prevent altitude sickness; I took it for that reason. Most everyone has pins/needles and numbness in hands and feet; carbonated beverages taste flat; appetite is usually reduced.

Thanks for your response. After all the testing, he has been diagnosed with pseudotumor cerebri and is on Diamox. The optic nerve swelling had been going on for awhile before the bump on head.
No if it were truly "minor" then it would not be a likely cause. Hopefully the ophthalmologist can shed more light on the problem. Good luck.
