I had a virus very similar to coronavirus in February. I lost my sense of smell completely and also my hearing in my right ear. My sense of smell has returned (although not as sharp as it was) but I am still deaf. I am so deaf in my right ear that if I lay in bed on my left side, so my left ear is muffled by the pillow, I can't hear dh snoring, which is a blessing to be honest but demonstrates how deaf I am as he is a very loud snorer!
I have done the otex ear wax treatment twice and used a neti pot to rinse my sinuses. Neither helped.
I also have pulsing tinnitus in that ear.
For obvious reasons I don't want to contact my gp, but its been 2 months now.
