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.
Having too much stress or anxiety can certainly cause patients to begin experiencing mouth and jaw pain, according to Dr. William B. Thompson DDS. A dentist in Tukwila, Washington, Thompson explains that this pain is typically the result of the patient clenching his or her jaw muscles throughout the night.
