My dad 80 yrs old. Had back surgery 3 days ago I brought him home this afternoon, he is having a lot of discomfort gave him his Norco pill , now he is seeing things and picking at the ceiling, he has been on the fentinal patch 25 mg but was taken off today. I am afraid he will get out of bed and fall, he can t do that on his own with out help, buthe might believe he is able to, I ask him if he is ok he says yes, but seems to fall back to sleep and starts talking and picking at things in the air, kind of scares me
