My Mom Is In Hospice And They Are Trying To

My Mom is in hospice and they are trying to manage her pain.. she is 92 and about 4'10" weighing about 65 lbs now. They had her on fentanyl transdermal 12.5 dosage and Norco TID, she did well the first week an all of a sudden her pain is no longer controlled and they discontinued the fentanyl patch saying she doesn't have enough fat in her body to absorb the med and have just gone to Norco QID.
