Thanks for putting your query over here.
If you are facing all these complaints since 1 month,first thing I would like to ask you is have you visited any physician and undergone any blood tests?Well,the clinical scenario you mentioned can be because of
viral hepatitis,typhoid that needs to be diagnosed through clinical examination,blood tests and USG abdo for
gallbladder disease or
appendicitis.Stool tests can be done to rule out intestinal parasites.
Is there any complaint of diarrhoea,
weight loss,decreased appetite,headache with neck stiffness?These symptoms may point to some other pathologies.
As per your history,you have got all complaints since 1 month,so taking just symptomatic like
paracetamol or anti emetics won't help.The basic cause needs to be found out,so visit your physician as soon as possible.You may be given with an antibiotic course if needed.
Thanks and regards.
