: : I have had this problem for approximately 6 years. Some times are worse than others and it only happens when I rest or try to sleep at night. It interrupts sleep on a nightly basis. Sometimes it sounds like a fire crackling in my ears and sometimes the popping is a muffled, distant sound. It affects both ears, but the left ear excessively. I have seen doctors, but know one knows what is going on. I need help.
