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.
Tetanus can also be the cause of this kind of pain and it can be very scary. If you suspect that there is a reason for you to have tetanus see your doctor immediately. Most of us do not think of arthritis as being a cause of any kind of jaw pain but it certainly can be.
