Obviously the most common form of pain is chest pain during a heart attack. Most are aware that this pain may radiate into the left arm also, but few may be aware that pain may be felt also in the area of the lower jaw on the left side. Usually this will occur alongside the more common chest pain but at times the only sign be of pain in the jaw. Patients who are experiencing a heart attack will usually complain of sweating, difficulty breathing and weakness with possible nausea and or vomiting. The pain is typically aggravated with exercise or exertion and relieved by rest. Left jaw pain in the absence of the other symptoms should certainly not be a cause for concern, but if in doubt an urgent assessment for a heart problem should be sought.
Jaw pain probably only occurs in a very small number (3.6%) of people with a heart attack.
