I took levaquin for one month, for that darn ear infection. This was after several rounds of other toxic antibiotics(3 months). I had gone to a disease specialist as I couldn't kick the ear infection. I hear you about being young and this happening. I had my first auto immune disease at 29 years old. I now have 5 and I am 61 years old. It has been a rocky road most of my life.
I do think that the PN can get better. It all depends on a good physician. I go see a physiatrist, who specializes in pain first. This type of doctor treats the whole person, rather than just one symptom after the other. She has helped me alot. I can also relate to the age issue, as I was angry when it happened to me at a young age. I had two little ones to care for. I know it is hard to look on the best side of things. In fact I had counciling, and still do at times to be able to cope better. I don't always do very good with my own oceans of emotions that follow illness and pain. I do relate to you, and I care. Wish I had some magic formula to ease your way. ginnie
