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.
Pain on the side of the face that can radiate to the head or neck may be indicative of the jaw malady known as temporomandibular joint disorder (TMJ). But in many cases, the problem isn't the joint connecting the jaw to the skull, but muscular tension caused by clenching your teeth while under stress. Before you schedule that operation, ease tension in muscles that operate the jaw: Open your jaw as wide as you can, hold for a few moments, then gradually let it relax. You may feel more pain initially, but that's a function of muscle tightness; the discomfort should dissipate as you work the muscles.
