My mother has chronic nausea, belly pain, and constipation. She is on Oxycodone for arthritis in her spine. She goes to pain management for this drug. She has been on it for over 7 years. She takes Linzess off an on for the constipation that it causes. Sometimes it helps and sometimes it doesn't. She has tried Miralax, stool softeners, prunes and prune juice. She has been to her PCP several times for the nausea and he gives her something for it. But it really isn't helping. Does anyone else have an elderly mother that is dealing with the same? We were told the nausea may be due to the constipation. But I am wondering if it could be something else.
