Beep sound and fungal infection.

Hi DOCTORS.. From last 1 month i am suffering from ear problem...Pain comes and goes in left ear .I consulted ENT surgeon...Bit ear wax was removed... Initially treatment was cefuroxime 500-bd Mountelukast fexofenadie -od Acetylcistine tab-bd Steam inhalation... Ceruklin ear drop.. And one nose drop.. I was continuously having beep sounds.. Than after two weeks i contacted again.. Now he removed some whitish substance from ear..Now he prescribed Amoxyclav 625.. And changed the ear drop and gave another.. But after three weeks still problem persist.. Now I consulted another ent...he told that it's fungal infection... Prescription Levocitrizine, paracetamol650(given for pain following pain caused by wax removal by succion).. And candid ear drop.. Asked me to swallow saliva frequently and to do valsalva.. But after three days still problem persist.. Please guide me what to do.. Mild pain in throat also..(not constant).. I am worried???
