What kind of laxatives have the drs tried? Has he been to a GI yet? My daughter was the same way with the screaming and crying with the bms. Granted, she has other issues as well. She is now on Miralax and it has made our lives so much easier. The Miralax pulls the fluids back into the bowels allowing them to pass easier. Have you tried any of the over the counter stool softners? My daughter takes the Miralax daily (3 tbs) and it works wonders. I hope that something works soon.
