Hi welcome to Health care magic forum.
Thanks for choosing H.C.M.Forum.
You had uncontrolled shaking from pelvic area, down the legs, cold chills
with extreme abdominal and pelvic pains.
It appears to be a urinary tract infection
, with or without stone in the urinary tract
. It may be malaria
also where these pains may be secondary to the chills.
I advise you to consult a physician for diagnosis and treatment.
wishing for a quick and complete recovery.
