Hi—Sounds like some of what I experience! That crackle sound in my ears is usually a sign of Low pressure and a doozy of an incoming migraine. Someone suggested looking into Ménière’s disease when I talked about these same types of symptoms. I went through a period of a few weeks where all sound was obnoxiously loud and it sounded like I was in a tunnel. Typically, I have very low blood pressure unless I’m in the midst of a migraine. Also, I live in Northern Wisconsin, close to the UP of Michigan and the Great Lakes. We get some wild weather.

Thank you for responding. I have been on Propranolol for over 30 years because of High blood pressure and it seems it hasn't blocked the migraines at all. I'm still taking Botox combined with Emgality (which replaced Amovig) and Excedrine Migraine Extra strength. This was a horrendously humid Summer with many break throughs. I did the nerve block injections about 2 months ago and they too didn't stop the breakthroughs. The cooler drier weather seems to be helping more than anything else right now. My balance has been ok, but the blocked ears is a sign that a doozy is on the way. I don't believe I have Vertigo and I'm not sure about tinnitus. When a migraine is in the making an early symptom in my ears is warning something might be coming. I do my best to explain the sensation. If you were to turn on an old tv without turning up the volume, you might here a very low pitched electronic hum as if the TV was powering up. This prevails in my ears when the barometric pressure changes significantly forewarning the coming of a storm and/or buildup of humidity. High heat like Summer heat enhances this and exacerbates the situation. I'm becoming anxious and wondering if I'll ever discover the answer for year round relief.

i know that before a heavy rain i wind up suffering more times than not.

Good Luck(auto drives me nuts) 😂
