I would think however, and this is NOT a medical opinion, that Gabapetin ( which also was developed for epilepsy) would be more helpful with SFN discomfort. I take 3600 mg gabapentin daily and it stops my SFN misery completely.

Just a thought. Mention it to your Hopkins doctor. However, perhaps the mutation in 'sodium channel' indicates Lamictal.
