Treat the opposite side in a similar manner. Flex the limbs strongly against the abdomen, holding them in this position a few seconds. In case of constipation, see Constipation Treatment.

It is always advisable in cases of rectal trouble to flush the bowels occasionally in case the patient is constipated.
