Rapid Heart Beat in Cats. Save to mypetMD. Supraventricular tachycardia (SVT) is a medical condition that is characterized by a rapid heart rate that occurs during times of rest or low activity (i.e., at times other than exercise, illness, or stress).
If you chew too much or subconsciously clench your jaws during stressful times, your jaw muscles can spasm and cause pain. Stress-induced clenching or grinding can cause slight misalignment of the jaw, leading to jaw, neck, or eye pain, as well as jackhammer-like headaches.
Headaches, muscle pain, muscle tension, tight muscles, and stiffness are all common symptoms of stress-response hyperstimulation. As long as the bodyâs stress remains elevated, one, or a group of muscles, can remain tight causing anxiety related muscle tension symptoms. Moreover, recent research has found that psychological stress can negatively affect pain modulation (the bodyâs ability to regulate pain).
