Thanks, Spaw. I have quite a while to think about those tests. I made an appointment today, and apparently it's real popular. I won't be going in until August 7.

as for other tests, I had an ultra-sound done on my testicles. I know what they look like, but I'm not sure my life is better for the experience.

Anyway, it's going to be a while before I find out why my eyesight is messed up. Actually, I know why. My optical nerves are swollen. Nobody knows what the cause is, which is why I was in the hospital getting tested. I can still see, and it isn't affecting my life. It just looks like a flash bulb went off in my right eye and the image won't go away. Thanks again for all the help. I let you know how things turn out after the MRI takes place.
