Hi Wooda, I am having No 10 on Friday & noticed some tingling at 8. My oncologist said last Friday she would stop at 10 if it became worse because sometimes it can get worse after finishing treatment. Yesterday I had numb toes, it has gone today. I have acupuncture every Monday & reflexology on Wed so think this is helping. I am determined to finish but will see this time next week. My nails are in good condition still, just a few have are slightly discolored. She told me to keep them painted at all times.
