The pain was excruciating and
traveled through my breast and
shoulder, but was gone in a few minutes and
I was able to
continue class. Also, I was in the desert for a few days and it went away but returned about a week later. I fairly certain it isn't stress/anxiety as the trip out of to
wn was not relaxing. The breathing seems better when I stand/worsens sitting do
wn, and I may have been standing more than usual on the trip. I am feeling so frustrated, scared, and depressed.
