The clinic atmosphere wasn’t exactly comfortable.
When doing back exercises, I felt like only my trapezius muscles were being engaged, and it increasingly felt like mountains were rising up, so I got the injections.
Unexpectedly, it worked well for tension headaches, and as an added benefit, it also helped me focus the effort on my latissimus dorsi when doing back exercises.
At first I got it because of back exercises, but these days I actually go get it when I get headaches. hehe
