Ketamine day 3

today was NOT a good day. my pain spiked so much. after iv fetanyl my pain went from a 10 to a 5, but the relief only lasted for about an hour and a half. My doctor was on duty today, so he spoke to me, and it seems he is really stumped and trying to figure out what to do next. The ketamine seems to help my upper body, but not my lower body. He decided to schedule me for another lumbar epidural block next Friday. Hopefully this will help, but in the past the relief has been limited from these.
