Have An Issue With The Ears, Could Hear An Echo Leading To Headache But Still Not Diagnosed With Specific Problem

I m having ear issues too. I have been to my PCP and an ENT. This is Day 22 and I m still isolating myself from normal everyday settings. I wasn t exposed to a loud noise, nor am I on medications. I m 47yo, healthy woman. My hearing test came back normal (not surprised). No signs of infection in the ear, no temp, no other signs of illness. I asked if hearing pressure could be an issue (thinking tympanogram... my son has had them numerous times.. he is hearing impaired). ENT said absolutely not. Sounds like a digitized echo in my ear, any external noise, or the sound of my own voice. Daily headaches from the noise.
