I passed a kidney stone a month and a half ago, and switched from a codeine-based painkiller to ibuprofen because of the constipation. (Also, for me, at least at the prescribed dose, codeine-with-acetaminophen/paracetamol gave less pain relief than 400 mg of ibuprofen. I'm also aware that morphine is significantly stronger than codeine.) The increased abdominal pressure from the constipation probably helped the stone pass a bit faster, but it also certainly seemed to increase the pain. On a side note, drink plenty of water. 42 is pretty young for passing a kidney stone. Working from home this past year, my wife would give me a hard time that some days I drank only 500 mL or so of water. (I drank plenty of coffee in the office, but cutting down on coffee while working from home unfortunately didn't translate into replacing coffee with water.) My urologist says I should be drinking at least 30 mL of water per kg body mass per day. Yes, most of our food is mostly water, but at least for me, that didn't cut it. I've heard people compare passing a kidney stone to childbirth, but I'm sure that's a gross exaggeration. A really bad hangover is worse, but a kidney stone is painful enough that I was pretty useless for 5 days and could only sleep in a really hot bath, and then only for about 1-2 hours per day. You don't want a kidney stone.
