I went to a podiatrist yesterday, she was very good and said that she would be spending the weekend reading up on Behcets.
What was really interesting is that she spied my favorite shoes that I have been wearing to appointments for the past 18 months. They are closed in at the front but have no back. She said that I am using (clenching) my toes to keep the shoes on and that as I have nerve damage already to my feet it is the worst thing I could be doing. Around the house I've been wearing Crocs. She wasn't really happy with that but could see how the cushioning would help. The important thing is I have to start wear closed in shoes or a strap.
Hope this helps someone.
