I was diagnosed with PID roughly a year ago and was screened for stds and it was negative, then i was given two anti biotics, but shortly into the regimen one of them kept making me sick so they gave me a shot in my rump, and i never made it to the follow up. but in the last months i have been to my doctor for urinary problems and i told her i had seen discharge and was tested for stds and had a vaginal swab done and all came up normal or negative could the PID have returned or never been completely cured?
