i have never checked my blood pressure during an episode. That's good advice and I will try to check it next time I have an issue. I don't go to the range, I work in a open setting prison so there are no guns. I'm 33 and have been in law enforcement for 13 years. I did expect the manhole lid to fall. I was watching it and did not think it would be an issue but the vibration definitely brought in an episode. Thanks for taking the time to help.
