Optic Neuritis worse after exercise?

[marie0610]

I was wondering if anyone experienced worsening vision symptoms after a strenuous workout. If so, how long did it last? Having some loss of peripheral vision right after exercising.

marie: What you are experiencing is most likely Uhthoff's phenomenon. This happens when symptoms (like ON) get worse after heat exposure, exercise, fever, or hot baths, etc.
How long does it last? Usually until you cool down. It is different for everybody. You may want to check into wearing a cooling vest for your workouts to keep your body temperature down.

Good luck!

I experience that too, and like Lisa said, it's just until I cool back down again, so, about 15 minutes. It's very normal for those of us who have damage to the optic nerve.
