Had a ruptured ear drum repaired in May of '09. Post surgery (Jan '10) have had a consistent problem with a sensation of not getting enough O2 into the body. Sometimes it seems I have to force air into the lungs. Granted my head was probably turned to the right for the duration of the surgery. Could any muscles be twisted causing swelling on nerves nearby or on the larynx? Any thoughts? Both the ENT and a family physician do not know why this would be the case. The ENT said this never happened to any of his patients before.
