I understand the difficulty all around. They can’t prove antibiotics cause PN or hurt those who already have PN; on the flip side, there’s no proof antibiotics DON’T hurt those with PN. And it’s not a major research interest. When I ask about it when I’ve been prescribed by dentist, eye doctor, and even my PCP, I get a confused look. I asked my Neurologist 2 weeks ago and got a “I don’t know” as I got in reply to several other questions I had for him. Bottom line is that those of us affected are all searching for cause and effects that help us or hurt us so we can adjust accordingly, whether we think it’s antibiotics, vaccines, coffee, or sugar etc. I have felt setbacks weeks after taking antibiotics and wish they could help us make more informed decisions. So for now, if I need an antibiotic, I stop taking them after a few days if I’m feeling better or if my legs feel weaker, whatever comes first. I won’t finish the prescription because I have to make a choice between the potential injuries of the decision. Luckily, I have had a couple of doctors say it’s not always terrible to stop them as it was once believed.
