Hi Diana, My progression was very similiar to yours, first one big toe and then the other , then the toes, ball of my foot, etc. I dont have muscle weakness though. They do get tired easily but are still strong. Also the botooms of my feet are very sore especially in the ball and heel areas and especially when i walk. It really feels like I am walking on broken bones. No cause was found for my PN after extensive testing, but I am sure it was toxin related.
