My husband requires a my fedding tube at the moment, he was sent home with one and asked to place it himself. Even though he followed the instructions from his doctor, after the tube was placed he suddenly started slurring his speech and becoming unresponsive, he couldn’t move ,’couldn’t control his limbs and lost control of his bowels and was about to faint. When the tube was removed he started slowly becoming normal again. What would cause this kind of reaction ?
