A quick update: my feet are much better. Nurse Jacque spoke to Dr G and he recommended adding gabapentin back into the mix. I took the first dose around 5:30 PM and my feet began to feel better right away. I don't know if pain from neuropathy comes and goes or is constant. (Mine has been pretty constant so far, which is why yesterday's huge increase in pain was such a blow.)
I will monitor the gabapentin + Lyrica and call Dr G's office on Friday to let them know how I'm doing.
