Hi, my mum had exactly the same thing last week. She had caught a bug prior to that and this is a build up of fluid in the inner ear-so drops won't work, you'll need to be prescribed some decongestant by your doctor - unless you are on high blood pressure tablets (they won't give you decongestants I think they interact badly) but you will get antibiotics instead. Go to doc asap cos my mums got much worse, she is almost totally deaf with it now and has been told it could take up to 2 weeks to clear. All the best
