Hello, So I can’t exactly remember how long it lasted 4 years ago. I’m thinking the whole thing was maybe a month or less. I do remember it happened around the exact same time and month now which I find weird. Besides stress I also think maybe weather (pressure) changes might be a cause of it too but that’s just my theory. I do not cope well with it. My anxiety has been through the roof with it. However I’ve been getting better at coping and mine will seem to be good for a couple of days where it hardly thumps and some days bad where it will do it all day. I do believe the magnesium helps though. I started it up again and the thumping has gotten a lot less. Also I know it’s extremely hard to relax while your ear is thumping but I’ve been doing everything I can to help my nervous system relax when it’s not. I wake up and listen to calming music, I use the calm app on my phone (which is great by the way) to guide me through meditations and relaxing my body, I take a walk. Try to do whatever you can to relax during the day when your ear isn’t active. I didn’t even realize how tense my jaw and face muscles were until I started doing these exercises! Do it even if you feel anxious while doing it. Over time it will calm your nervous system. Once again, I’m no doctor but this seems to be working for me. If mine starts to come back or get worse again I’m going to look into acupuncture. Ive heard some people had luck with that too. I hope this helps a little. I know how maddening and stressful it can be. My ear doctor who has dealt with this before says it is self limiting and the majority of times just goes away. Hang in there!
