My wife just has spinal surgery and is on a combo of oxycodone and Tylenol for pain relief. Her stool is dark sort of grainy soft like baby poop and really stinks.  Her hemorroids are killing her.  She has a supository for the Hs.  I have been giving her metamucil in the evening along with a colace and miralax.  What kind of food should she be eating?
Oxycodone cause constipation. Try to minimize the dose. She should take more of green salad leafy vegetables and soft diet. Avoid having high protein diet for time being. Please take lots of water. More of walking around. Things will improve over a period. If pain is under control then opt for non opioid painkiller. Thanks.
