Yes, I am scheduled to start Keytruda next week. I don't know how the side effects will affect me as of yet. I still have leg pain from the Chemo eventhough I finished chemo 5 weeks ago. I also take ibuprofen and tylenol. The oncologist is conservative with the pain medication. I hurt most of the day and night. I also have severe neuropathy in both hands and feet, caused by the chemotherapy. It has severely affected my quality of life. I can't even put my earrings in my ears.
