Dear Sarah:
Sorry to hear about your problem. I am not sure what to tell you. Yes, things might be related to a post-viral syndrome, but also things might be related in some way to the lightning event. Not that the lightning caused the leg pain, but the event probably changed the neuronal sensitivity to various stimuli, and the viral problem just upset things enough to induce some of the symptoms your experiencing. Although many would say that your problem might be lyme, with a negative test (I am assuming that it was the ELISA) I would think you might want to have the western blot analysis performed. If your pain is neurogenic I would think that neurontin should help. Just for your information, the ANA would have to have a very high titer to mean anything, and if the titer is low (dilution of 1/16 for example) then it is likely not worrisome.
Sorry I am not much help.
Sincerely,
CCF Neuro MD
