Know a little about how you feel. Back pain sent me to the doc 3 years ago, turned out to be renal cancer moved to my spine. Stage 4. 3 back surgeries later, and 2 years of Opdivo infusions here I am. Had a surgery in April that removed 3 vertebrae, T6, T7, and T8. Cage on the front, 4 rods and lots of screws in the back. Incredible post surgery pain, but after a week it was less than pre surgery. Started the Opdivo every 2 weeks at first, after a year and a half they went to every 4 weeks. Luckily I have no side effects from the infusion. 6 weeks out I am transitioning from a walker to a cane. Leg strength coming back. Will begin proton radiation therapy next week, not sure how many treatments. After that I will go to outpatient therapy to get my legs back under me. I was just getting my legs back from the first surgery in Feb. 2016 last summer when it came back. This will be the third round of radiation, so they have to be careful with doses.
Sorry to derail the thread with my own issues, to the op and other patients here, hang in there, stay positive and kick cancers a**.
