I developed T in 2008, but it was very mild and with CBT it became practically nonexistent. At the time I was living just outside Houston, TX. In 2021, I retired and moved North of San Antonio which is called "Hill Country". It is a beautiful place to live, but my T has become noticeably louder (High Pitch). This area is about 1300 feet above sea level, and is known for Allergy's 12 months a year. About a week ago, I had to make a trip back to Houston for a few days, and I noticed that my T had returned to a much calmer base line as it had in 2008. Does anyone know or had experience with location changes. Houston is not much above sea level and here in Hill Country, Spring Branch Texas to be exact, we are approximately 1300 feet above sea level.
