Hi everyone. I'm 21 years old, no known health problems and not on any medications.
About a week and a half ago I came down with a cold. A couple of days later I woke up to find that I was deaf in my left ear. I just assumed it was mucus buildup from my cold and would clear up once my cold did. However, it's now been a week and I'm still deaf. If anything it's getting worse. I also have tinnitus in the same ear. Initially I peered in my ear and couldn't see anything, but today I was having another look and saw a yellowy/white substance sitting in the ear canal. I managed to take a picture. It's not the best quality-wise but I hope you can make out what I mean.
Does this substance indicate infection? Or is it just weird looking earwax? My ear doesn't hurt at all but I have been feeling a little unwell for a couple of days. Nauseous and generally a bit under the weather. I have booked a GP appointment but unfortunately they cannot fit me in until Thursday. Should I call them again and asked to be seen sooner? I've never had an ear infection before so have no idea what they feel like. 
Thanks in advance!
