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.
But some types of tooth pain are caused by stress. If you're stressed to the point of clenching your jaw and grinding your teeth, you can develop tooth pain associated with the temporomandibular joint (TMJ). The TMJ is the joint that hinges the lower jaw to the skull, enabling you to eat and talk.
