Core apain: There are numerous causes of core pain. Are you an athlete, dancer, or otherwise participate in strenuous activities? Often, core pains are due to stretching of muscle ligaments from such activities. Without further history, it is impossible to pinpoint the cause. If these pains continue, it would be prudent to consult with your doctor.
