Hi welcome to Health care magic forum.
Thanks for calling H.C.M.
Severe cough with sputum
, vomitings, and body pains means there is severe infection in the chest, and fever
might be there though the body is cool.
I advise you to consult a doctor for diagnosis and treatment, other wise it may lead to chronic infection and may involve the heart as well.At least it is urgent to controle the vomitings first.
chest besides other routine tests for confermation of the disease may be necessory .
