I was speaking on the phone with mum on Tuesday night and she mentioned that dad has gone deaf in his right ear. He simply woke up on Monday morning and couldn't hear anymore. They were planning to see the GP on Thursday since they already had an appointment for something else. My folks didn't seem very concerned. In fact, dad was downstairs in the kitchen preparing food. Hmmm....I told her I'd look into it.
I went online and found some credible medical websites about sudden hearing loss. And what I read didn't sound good.
I called mum back and told her to take him to the hospital. They did some tests and put him on steroids and it's now a waiting game to see if the hearing will recover. Apparently he is now totally deaf in the right ear and if the hearing doesn't recover, he'll have to get a hearing aid.
