I've had a cold for the past two days, I was also sick a couple of times on saturday night. I was feeling better today until for no apparent reason my right ear popped like I was on a plane, that was two hours ago and it's still not right. I've got a muffled buzzing sound and it's sore, especially if I cough. I've tried lying on my side to clear it but it didn't help, I feel sick and a little disorientated. I had no pain before a couple of hours ago
