Hello, I have had an ear ache and pressure in my left ear for over 2 months. I had a very bad cold, virus to start. I have taken 2 rounds of antibotics. I went to the ear, nose & throat doctor, but I am unsure of his diagnoses. He put me on another round of antibotics and steriods for 10 days. He said my inner ear is swollen, but I do not have an ear infection or sinus infection. I have chronic neck, shoulder and back pain. He told me if this doesn t get better in 10 days then I would need a CT scan. What would they be looking for?
