I fell last week mainly because I have Guillain Barre Syndrome and so do not have much balance control although I have had it for 15 years and it took 6 weeks before I had a diagnosis! My right ankle has always been weak due to several sprains. Now it is it still swollen, I am applying ice and elevation. Any other brilliant ideas. Thank you.
First confirm diagnosis of Gullies barre syn Chat Doctor.  If it is the case then treatment modalities available are IVG or plasmapheresis, both are equally effective. Your ankle sprain is not due to GBS.  Take analgesics, apply crate bandage.  Why don't you consult the nearest neurologist to confirm the diagnosis as time is important factor for treatment outcome Hope my answer will help you. Take care. Don't forget to rate me.
