It could, since I did take both Septra and then a short course of Cipro to clear it up and I know about PN and antibiotics. But I am really suspicious of the infection itself doing possible damage. It was so very intense and I started having physical problems such as extreme pelvic muscle pain before I even took any drugs at all. I want to know if there is any possibility that my nerves were traumatized by this infection and if the ten months in between the infection and the start of PN is too long to connect the two. I don't care what the neurologists told me, I'm looking into everything that happened to me within the year of getting PN, even if they dismissed it.
