I have Neuro-Behcet's, diagnosed at the Mayo Clinic...Because of my extensive experience over the years , I know it is a waste of time to speak with any doctor who has no experience with treating N-B.. So, if you have an experienced doctor - my question is what could be going on to cause leg pain so severe that I can no longer walk without a good deal of pain? I know other N-B patients with the same type of thing...some are now using wheelchairs...and it is literally life-changing now that I cannot help around our small farm anymore....Thank you for your time. michael murphy
