My son had the same problem and was 10 years old when, finally, for a different reason, we took him to a chiropractor. Strangely enough, a few months after treatment, the poop problem went away. He still goes once a month to the chiropractor. Evidently, a nerve that controls that urge to go was suppressed and when the pressure was taken off of it, everything was good. During the problem, he had embarrassment and acted like he didn't care, I think, because he couldn't figure out what was happening in his body. I don't know that this is your son's problem, but it's worth a looksie. Good luck.
