It can happen in one to three areas of
my body at a time, in varying combinations—it can occur in my jaws (clenching my <span style = 'background-color: #dae8f4'>teeth</span>
), tongue, back, hands, arms, buttocks, legs and feet. I don't realize I'm doing it until it really starts to hurt! Once I'm aware that I'm tensing, I can make the muscles relax, but most of
the time, it just happens again after 10-30 seconds, or if not that soon, a few minutes later (either the same part of
my body, or a different one).
