Ok I Am 50 Yrs Old And Have Had Pelvic

ok i am 50 yrs old and have had pelvic inflammatory disease since i was 18. Now that i am older i have very few outbreaks. But neverless anytime i change partners or other misc? i sometimes have all the symptoms. bloated, cramps, fever, breaking out, painful and scanty urination, psainful sex, smelly discharge ectt... wen i have all the symptoms of course i know i need either the metronidazle or tetracycline. I know my body and am quite familiar with my condition. Ok i get new insurance and i go to gyno and no one wants to give me my medicine?? for the first time? no they want me to get a colonoscopy? because she said i have a hemoroid. are u kidding? wat do i have to do to get my meds? im going on 6weeks being inflammed now and idk wat to do. should i just go to the vd clinic? or how else may i obtain my medicine?
