You are suffering from fullness in ear, pressure and sudden increase in amplitude of sound( recruitment phenomenon), so it become intolerable.
This may be due to noise trauma. But your audiogram is almost normal except very high freqency. This sensation will improve with time.you can continue your shows once you are symptomatically better, with use of ear plugs.
Tab.betahistine 24 mg two to three times daily for 2 weeks will help you.
Hope this helps
