Have you seen a podiatrist? I have the same condition except mine doesn't sound as bad as yours. I was prescribed a metatarsal insole to keep the pressure off of the nerves. It puts the pressure further back on the foot instead. My foot shape tends to put a lot of pressure on the outer toes. I also used to walk around a lot barefoot on concrete, hardwood floors, and tile floors and this caused (or helped cause) mine.
