This requires for a good understanding that a pain starting from your jaw line and extending to your shoulder and left arm can indicate coming on of a heart attack. In fact, a man clutching his heart due to unbearable pain is a classic depiction of heart attack in reel life. Difficulty in breathing is often an accompanying sign of heart attack in women.

Also, in women, the pain in the left area of the body can be a significant sign of urinary problems or an infection in early stages.

Any unusual amount of intensity of pain in abdominal area or stomach region should not be ignored by women, even if they are menstruating.
