Hi,I am having ringing sensation in my ears for last 15 days, my audiogram and impedance tests were fine showing little congestion,otherwise I m healthy,I took augmenting antibiotics for 10 days on my doctors prescription but still the sensation persists,now she has asked me to take omnacortil 10 mg for 9 days.does this steroid really help me at this time? Are there any side effects,please help.thank you.
