I had a ear infection in 2022 that was different than any previous ones, and it didn't respond to Amoxicillin, which always worked on the other type. It also didn't respond to a different antibiotic a Doctor at the Loma Clinic gave me.
I ended up going to Dr Nikom Mee-In, an ENT at Pattaya-Bangkok. He did a great job fixing me up. In addition to the infection It turned out I also had a hole in my eardrum.
