I noticed today that pressing muscles behind my ears makes my T louder? After done that my T started fluctuate like crazy... Does that mean something? I don't even realize why it's changing constantly and sometimes it's very quiet? I haven't heard that anyone's T would change during the day as much as my does! It's like when I listen it right now during writing this, the noise is different after I have finished this sentence. One thing that bothers me is that when I smoke, my T is very quiet after that, almost like it doesn't even exist??? I have read that nicotine relaxes muscles? I know nicotine constrict blood vessels and that is one reason why it causes spikes to many T-sufferers but I don't get any spikes from smoking. I'm very confused now! Try to understand my text, I wrote it in hurry
