I had a sudden loss of earing in left ear 3 days ago. Went to a quick care center yesterday was told most likely TMJ, sinuses were clear. Was told that with alleve and a mouth guard it would be better the next day. Did both and still don t feel better. I don t think its TMJ. Neither my husband or I are aware of teeth grinding at night. It seems to feel better when lying down. Have taken decongestants with no relief. Migraines were mentioned but my migraine medicine did nothing either. Have spent all day in bed as this is only relief I seem to get. Also- low pitch noises bother me. There has been no trauma to the ear.
