My husband is having problems with constipation. He was put on a fiber drink similar to benefiber several weeks ago. He had a small bm 5 days ago but was having extreme stomach pains and went to the hospital. At the hospital they put him on bental for pain and miralax as it showed on the x-ray he was still severely constpated. As of now he still hasn't had a bm. He says he can now feel it in him. What should he do now?
