Hi welcome to Health care magic forum.
You have got pain in the lower abdomen, and back, shooting up to the shoulders. No fever
or bleedi ng, but chills
Most probably it is urinary tract infection
, or amoebiosis. I advise you to consult a physician for diagnosis and treatment. You may have to take M.R.I. for confirmation, besides other routine tests for confermation.
Wishing for a quick and complete recovery, and thanks for choosing H.C.M.F.
