I Am A Chlamydial Patient Of Nearly Seven Years. My

I am a Chlamydial patient of nearly seven years. My doctors have pushed themselves on me civilly, being dishonest, claiming to me that I don't need antibiotics. Initially I was given antibiotics, but did not get prescribed the Erythromycin and did not successfully eradicate the bacteria completely hence. I'm considered as having "Reiter's Disease" now. Do you think it would be taboo, contraindicatable, for me to try the Erythromycin now, even though I'm thoroughly diseased, infected.
I'm in possession of a prescribing for 240 500mg tablets of Zithromax, (4 tablets twice daily for 30 days), but the Zithromax is too expensive, my insurance doesn't pay for it. And I'm having trouble with the pharmacists, with counterfeit products, being blackballed. I don't know where to go.
