Welcome in H.C.M.
I have gone through your query regarding fever
and sore throat
not responding to treatment. As you said you are taking augmentin
by the advice of your family physician but fever is still there.
Your wife may be having some other factors as running nose, sinus infection
, chest infection
etc. and there is also possibility that augmentin may be resistant in her infection.
It will be better to consult an E.N.T.spcialist for thorough examination and necessary investigations to make final diagnosis and treatment.
