Deb, same with me, I've lived on the far southern end of the Jersey shore and the mosquitoes were horrible! Our town sprayed early evenings and kids ran behind the truck. Who knew? For me, the take-away from all of this is that during our lifetime, we encountered toxic chemicals, heavy anti-biotics and other medications that are possibly linked to PN. We can't change the past. And besides, even if we are able to determine the PAST cause of why a person develops PN, what change will that make? No med will fix this. In my case as in many others, according to my neuro doc, the damage is done. Again, sharing of information in this journey is helpful.
