I agree. Life is a gamble, and since there is no reason to believe that Alan is extremely low in B12 and in desperate need of at right now, I would continue with the current treatment. Then, later on, I would supplement B12 as a preventative and on the chance it might also help.

The new symptom could be a coincidence, but it could also be nerves responding to treatment and working to repair/regenerate. The timing makes repair a good possibility,but time will tell.
