Hello Asad,

This case is moving toward cham, puls and opium

Cham has unable to hold head up, head falling backward, carried desired to be, impaired hearing (listen loud), squint eye, dim vision, scrof head, delay denitation, inactivity of rectum due to spinal cord affection result in mild constipation, when stool accumulates in rectum then it expels due heaviness and not due to natural urge which makes stool difficult to pass (you are calling it constipation)

Confirm cham after reading more from materia medica... I hope this will help you....
