Larium
Started on the death ship in the 80s after a quack syringed my ears when I had an infection. Larium made things worse especially with other parts of my body/brain.
Loud noise..night clubs..motorcycles ..etc and aspirin make it worse.
One ear only..right ..was a FO for most of my career.
Avoiding noise and wind noise helps.
NLP and trance music as well..had problems sleeping for years.
Audiogram normal for my age but have had problems understanding speech for years.
Use positive thought techniques so only a nuisance..lucky to still be here.
Good luck
