Sounds like a lot of sensory symptoms, as described in this website:

Spinal lesion attacks can take a LONG time to heal from, and I have found them to follow a distinct pattern for me; approx 6 weeks of escalating symptoms, followed by 6 weeks in the recovery stage. Ultimately, I count on about 3 months of major fluctuations, but then several more months (12 - 15) before I know what I have left to deal with from that attack.

Did your October attack follow a similar pattern (6 + 6)?

It sounds like there is new activity, which could be from the same (or a different) lesion. If there was 30 days between the recovery phase and these NEW symptoms, it would be considered a new attack. Sometimes it's hard to tell though, cause those attacks last so long.

I have experienced most of what you described; shock sensations, hypersensitive to touch (it can hurt ), numbness. I am very sensitive to drugs, so I haven't tried anything but Naproxen for the inflammation. Some people find neurontin helpful, and others have resorted to narcotics if it gets too bad.

How long have you been on B and how many attacks have you had while on it? It may be your body isn't favoring that particular drug.
