Not diagnosed. Ear infection August 2015. Soon after heartbeat sound in left ear started September 5th. Sinus infection in late September and again in October. Primary care doctor sad sound should go away since I had fluid in my ears but just keeps getting worse louder. Sometimes I feel I can't sleep at night and get anxiety from the noise in my ear. Need to go back to ask for referral to an ENT. Would like advice thank you.
