Very rarely there is more than a minor and transient discomfort experienced by some people. Your therapist will be able to put you at ease and answer any of your concerns. If you feel uncomfortable in any way, please tell your therapist. Occasionally the Colon may contract and give a colicky sensation but such episodes are usually brief and easily tolerated. These minor cramps are due to tissue in the Colon being dehydrated and or a sign that the body is releasing toxicity.
