I just had a ganglionueroma removed by vats from the spine near the aorta I'm not on narcotics anymore but still in pain should I ask for more? 3 weeks

Try to avoid. Better ask your doctor for.
Pain medication. . You were never on narcotics (this implies illegality)- you were on opioid pain medication. Since you still have pain after 3weeks it would be reasonable to provide a different pain medication for another 3weeks. After this it will have been 6weeks -well healed and you not require pain medication.
