Impacted/constipation help

Alexa • Micah Tyler born 08/31/17 💙

My son (he will be 1 next month) is very constipated, he had xrays done today that showed lots of hard stool backed up and huge pockets of gas behind it. He is extremely uncomfortable and since he is blocked up he's been having frequent watery stool and is getting a painful rash under his penis. He has never had diaper rash before or constipation so I'm looking for more ways to help him. The dr advised suppositories today so I gave him one about 3 hours ago and he still hasn't had a bowel movement. I also gave him some diluted apple juice and tylenol for pain as well as brodeuxs butt paste or whatever. Is that everything I can do pretty much?
