I mostly have T only but yesterday it spiked and my tension in neck was also more intense. I noticed something weird, I started to hear my ear breathing. (only one on the side with more tension) Changing a position finally settle it and it went away. It was not synced with the heartbeat. I experienced that before I had T few times. Is this due to tense muscles? This morning I woke up and it was quiet and after moving it started to breath again and then went away.
