pain
"I was prescribed this medication for pain management after lithotripsy surgery for multiple kidney stones, and it worked exactly as prescribed - knocked me out and killed the pain.

BUT - after 3 days using this medicine, I was extremely constipated - even though I was eating very little and drinking large amounts of water to help me pass the remaining stones.  I'm not talking about being mildly "backed up";  this was quite painful, and I was unable to sit or lie down comfortably.  It required a full bottle of magnesium citrate to resolve and if that hadn't worked I was heading to the ER."
