I'm glad to hear that you seem to be getting on the right track (and not going back to that horrible PT program).
I was put on Neurontin for a few months and it was absolutely useless at relieving the pain for me...but I know a lot of people DO get relief so it's just hit or miss. It also completely knocked me out, and unlike the Lyrica that side effect lasted for about a month instead of just a few days. I was even falling asleep while driving...which was pretty scary. But everyone is affected differently.
Hope you start to feel better soon. I think there's nothing worse than getting sick on top of being in pain and trying to start new meds, etc. Fingers crossed that you get better quickly and that the new program works out better for you.
