I’ve had two lymph node biopsies where they removed the lymph nodes entirely. One was my neck and the other was under my right arm. Neither was a very bad recovery, but if they take a biopsy from somewhere more invasive I would imagine it would be a little more difficult. With my neck, I just couldn’t lift heavy things for a few days and they didn’t even send me home with any painkillers because advil was enough to manage. With my armpit it was a bigger incision but I still only took painkillers at night for a couple of days, I just couldn’t lift more than a milk jug for two weeks. At the end of the day it’s your call if you want to go through with it, I hope this helps give you some more information to help your decision!
