The Eustachian tube is a small passageway from your inner ear to the back of your nose. Every time you swallow, yawn, or blow your nose, the Eustachian tube opens and allows air to pass from the middle of your ear to the back of your nose. This process equalizes the pressure in our ears. If this process isn’t working properly, you might be experiencing Eustachian Tube Dysfunction. This dysfunction can cause crackling or popping noises in our ears. The tube is lined with moist mucosa, and inflamed Eustachian tubes often get sticky, which causes the crackling and popping noises when the tubes are moving around. If the inflammation is serious, it can be easily treated with steroid nasal sprays. This info is from audicus.com, new to me too. I have crackling noise occasionally too even without swallowing or blowing nose, but they don't last long thankfully.

I get clicking in my ears when yawning also a lot of ringing in my ears. My neurologist explained it to me best by saying having fibro is like having the volume turned up on everything in your body. Pain, heartbeat, clicking sounds, ringing, literally everything is amplified. Not sure how to help you, this is a frustrating syndrome. Hope it resolves itself soon!

I have that too. Mine is from TMJ disorder - I grind my teeth and have to wear a mouth guard. I have ringing in my ears that has been relentless for almost two weeks now. It’s driving me crazy!

Hi Yes it have had this for years and yes it’s very annoying
Like Sadie Sian in her answer everything seems amplified with fibro like your volume is stuck on loud constantly
Weather it be noise in ears stomach heartbeat pulse or pain
I’ve lived with this nearly 20 odd years and very sorry I’ve no answer for you
I’ve tried all my own and everyone else’s remedies but still suffer
One word of advice is never ignore anything to do with your ears always get them checked out,
I lost 60% of my earring in my right ear from a virus thinking it was just another ear infection
If you ever find something that works please pass it on 😇
Happy Easter 🐣 to you all

That is a symptom of tmj. It is a symptom of fibro. It makes your jaw click when you open and close your mouth. Do you get pain in your jaw too? I have had flare ups on and off for years. It can become really painful. I always hear the clicking before a flare up. Sorry. I hope yours don't start causing too much pain. Hugs
