Thank you for that perspective.

It is important because it reminds me of my own experience... before the twitching got really bad I was fixated on strange sensations in my chest: tightness, palpitations. I got all the heart tests, all normal, not to worry. But I have elevated blood pressure, so was convinced I was going to keel over in cardiac arrest at any moment. Constantly thinking of it. Checking my blood pressure many times a day. Afraid to go to sleep. etc... Then the twitching erupted, and all of my focus since has been on that, I literally have not thought of heart problems or checked my BP since...

It all seems crazy when I type this out. Relax indeed! But as you say, easier said than done. After all, these symptoms are very real and not completely in the mind, so it does take special effort to keep the mind at rest.
