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.
Facial pain can be caused by an uneven bite, meaning that the jaw muscles are not working properly. When these muscles function inefficiently, they experience signs of stress, including pain, swelling and discomfort. Because the jaw muscles run from ear to ear, symptoms of jaw distress may surface in the face.
