Hi Jan - Have you tried ****** and find a list of clinics or doctors for PPS? I agree there are not many out there... Very difficult to find one that believes or wants to know... It is very sad.
What I have researched is when someone with PPS gets injured or has surgery takes twice as long to bounce back. So sounds like with your foot drop you will need a brace- I have one for my left and will be getting one for my right foot in the future.
Glad to hear from you- and best to you to find a doctor. Be careful walking and know PPS is 'real'-
