Hi, Welcome to Health care magic forum.
It appears that he had a fracture
or the sprain
of the ankle.With any sort of heavy pain it is possible to have chills
and feverish feeling.
I advise you to consult an orthopedic surgeon for diagnosis. You may need to have an M.R.I. of the ankle for confirmation.
Take more of green leafy vegetables, pulses, sprouts,and
protein rich foods for early recovery.
Wishing for a quick and complete recovery. Thank you.
