@suemer Thank you for letting me know.. I have alot of Gastro problems, including a strangulated colon,and one of them is also having the vagus nerve effected as well,, I have passed out when trying to have a bowel movement.. I had it under control ( for the most part) before my hip surgery,, I was using a "squatty Potty" but cant use it with the pain I have in my thigh and hip,, I dont know if that will help you and or your son,, but give it a try.. Bed bath and beyond,, with coupon,, end up with good price..
