Hi welcome to Health care magic forum.
Thanks for asking a question to H.C.M.F.
You had abdominal pain
since few weeks. some times light and some times heavy. Some times pain radiating to left side of chest. You also get pain and numbness
of left leg. Pain in lower abdomen is constant, Period is late by 4 weeks. and you have got a eating disorder
As pain is constant in lower abdomen, and coming down to legs, it appears to be the urinary tract infection
, or stones in the urinary tract
. Other causes are worms in the abdomen, if female, pelvic disease may be there.
I advise you to consult a surgeon for diagnosis and treatment.
