My ankles swell but it is a byproduct of my BP and kidney condition caused by my cancer. I have had extensive ongoing physical therapy since being diagnosed with CIDP so have not had problems with atrophy. Hot weather makes my ankles swell more. Hope someone else has a better answer to your problem.
My ankles swell and I try to massage my legs, ankles and feet during the day to keep the circulation going. My physical therapist suggested it and it seems to help a lot.
Keep it going!
much appreicated
