Oh no, no no! The feeling you get before performing is NOT the same thing as a health anxiety thing! It's 2 totally different things! Let's say you were thinking you had a certain disease and the symptom was a tingling leg and bad pressure pain in your stomach. Let's say you had the tingling leg and you started dwelling on the fact that you HAVE "that" certain disease. You'd then keep thinking, "But my stomach is fine" A few days later, "But I THINK my stomach is fine" a week later, "Hmmm, I'm getting a little pressure right under the breast bone... oh no! I AM getting that disease!" Then you start dwelling on your stomach more and more.... you start pressing it, you stand in front of a mirror to see if you are having any bloating... you eat and then concentrate to see if eating made that pressure worse... in time you really DO get that pressure pain and it gets worse and worse, now you have yourself convinced you have "that" disease. Then you start googling to see if there are any other symptoms of "that" disease, Ah ha!! You find one lone site that says an aching jaw can be a symptom... in time you get the aching jaw... that is what health anxiety is all about.
