I am having the same issue. It has taken me a while to figure this out. (Slow learner, I guess) I bought black PBPs 03/20 to replace my existing workout earbuds. Shortly after, Covid shutdowns caused my gym to close. The gym reopened in May, and all summer I was complaining about what felt like water in my ears, and ear itching. I swim a lot, so I thought that was the problem. Towards the end of October 2020 I got a bad ear infection in my left ear. I went to the Dr, the swelling in my ear was so bad, he couldn't see my ear drum. My right ear was hurting, but not as bad, and my middle ear and tubes felt inflamed. The Dr gave me antibiotics and antibiotic drops. The pain was terrible for the next few days. After a few weeks the serious infection subsided, and I was back at the gym. It never went completely away, I still had crusty ear canals, and severe itching. It also felt like the infection moved to my right ear, but was not as severe. Eventually behind my ears, and the top connection of my ear and head had what felt like cuts. I was trying everything to figure out what was wrong, my glasses, shampoo, etc. Last week I came home from the gym, and my ears felt like they were on fire. I searched, and found this topic. I am so grateful for everyone that has posted here. I am so grateful to finally know what the cause of this is. I am in the midst of my second ear infection, but at least now I know what is causing this.
I have another symptom that has been going on since my first ear infection in October. At the same time, my tongue, specifically my taste buds are irritated and swollen, additionally the roof of my mouth always feels slimy. This is consistent after I brush, use mouthwash, etc. It seems to be flaring up more now that I am on my second ear infection. Has anyone else noticed these symptoms?
Thanks again everyone.
