Hi Loula.. If I may interject here it may help put your mind at ease as little.. Although the needle biopsy sounds scary, it’s a duck walk (or is it cake walk), whatever!! They use a local and I didn’t feel a thing, not even afterwards. The access port is an easy procedure and well worth it. It saves getting that uncomfortable darning needle in the arm, easy all the way around and you won’t regret getting the port. Anti nausea meds helped me quite a bit when I was taking the chemo drugs. I did not tolerate the chemo drugs and refused to take anymore. Went on straight Keytruda, side effects were minimal and I didn’t need the nausea infusions. Everyone is different. Sorry I can’t help you on the loose fitting pj’s, nurses in the infusion room threatened to lock me in the closet if I showed up in my sleeping attire, I don’t wear any!! LOL.. You’ll handle this, stay strong and never give up.
