Thanks for the link, Lyon. It seems there is no conclusive evidence exercise makes the disease worse but may worsen symptoms.
About a month ago I walked, shopping, about a mile, and wasn't tired. Next day the top of my right foot went numb, next day up the side of the right leg, all new symptoms, neurologist wasn't sure about an attack or just from walking. It was an attack and got Solu-Medrol for it.
It would have been so easy to say the walking brought on the attack and give up or greatly reduce the walking.
Walked that same mile Sunday just fine but it has taken until today to get my energy back. No new symptoms of an attack though.
I'd gone to a two-day convention in early March that required long traveling, lots of walking, meeting new people, lots of new information thrown at me in a strange environment, most stressful thing I can imagine. It took a week to recover energy wise but no new symptoms to suggest an attack.
I really think there's a two-year-old "up there" pulling the strings at whim and I'm the puppet. Until someone comes up with a better answer as to what does and does not cause attacks, the story "fits" my situation perfectly.
I don't think of fishing as exercise but anything that gets one out of the house and focused on something else but the disease has to be beneficial.
