Hello, sorry to hear about your ear. I am having similar issues. Mine is random thumping throughout the day. Some days are worse than others. Sometimes it’s a lot of thumping which makes me anxious. My ear doctor also said it was spasms of the ear muscles kind of like an eye twitch in the ear. He recommended magnesium. I started to take it and it did help for a couple of days and I didn’t take it last night and today the thumping is back. If it makes you feel better my doctor said it is usually just goes away on its own over time. I also had this 4 years ago and it would thump all night and I couldn’t sleep and it made me so anxious. One night I layed down and slept with my hand on my bad ear and applied a lot of pressure and the thumping stopped! Shortly after that they went away and didn’t return until now. I’m hoping it goes away on its own soon but the magnesium does seem to help a bit. Please let me know if you find anything else that works.
