Is there cancer pain so intense that it cannot be controlled by any medication at home? what do they do in a hospice for it?

Yes/No: Pain medicines come in the form of tablets(oral use) or injectables which can be given under the skin(Sub Q) or given IV. Of these chocies SubQ and oral can be easily done at home but IV therapy requires a professional, frequently a Physician, who may be limited in availability, yet it can be arranged. It is all a matter of how best to keep patient comfortable. IV Pain meds can control any pain.
