Need some support

So just wanting to know if there is anyone else that has been diagnosed with PID (pelvic inflammatory disease) I was told 4 years ago I have it on top of a 4cm ovarian cyst. I was treated but I’m still in constant pain, I have gone to two different doctors but both of them have pushed it off as ovulation/period cramps. I know it’s neither of those as it’s constantly. I’m usually in tears when the pain is at it’s worse. Have had sonograms done have don’t see anything wrong and have done blood work and nothing. Just wanting to see if I’m not alone. I am on a support group on Facebook for this but they all have the same problems with no answers.
