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.
Types of Jaw Pain. Temporomandibular Joint Disorder (TMJ). One of the more common causes of jaw pain, TMJ usually occurs as the result of a problem with the bones, ligaments, and/or other tissues that make up the temporomandibular joint, which connects your lower jaw bone to your skull. TMJ may cause jaw pain that feels like a toothache, headache, or earache. Teeth Grinding (Bruxism). Teeth grinding can cause jaw pain, and, since many people grind their teeth while they are asleep, you may not be aware that you're doing it. Some research suggests that up to 8% of adults grind their teeth during sleep.
