Hi welcome to Health care magic forum.
Thanks for calling H.C.M.Forum.
You have protruding stomach, pain in the left, lower ,continues to the front of pelvis. No apitite, naussius. you have got lupus
Pain in the left lower abdomen, radiating towards pelvis always suggests urinary tract infection
or stone in the urinary tract
You must use some anti spasmodic and antibiotics if there is time for scaning, for being comfertable in the mean time.
I advise you to consult a urologist
for diagnosis and treatment. You may need to have U.S.scaning besides other routine tests for confirmation.
Wishing for a quick and complete recovery.
