I wish I knew why movement like walking or running makes my PN better. If I even think about standing in a line it does make my blood pressure does go up. I too have the flare ups as soon as I stop running and take the shoes off. Sometimes this can last for the whole day but the advantages makes it worth it. I feel better, much more able to deal with the bad days, helps with my weight and my attitude about myself. Now I have chronic hip bursitis so I'm weight lifting and riding a stationary bike. Not as good though.

I too swear it's blood flow but I don't have a clue if that's it. All I know is if I'm paper thin and run about 20 miles a week I'm so much better off. I haven't been able to say I'm there for 2 years though. Weight gain and limited exercise are the culprits.
