I'm facing repeated episodes of pid even after completing the multiple rounds of antibiotics since one year..I tried alot of different and same antibiotics but didn't fully cure..when I took antibiotics my lower back has gone for sometime but after completing antibiotics course back pain comes back..after getting infected i didn't make any sexual contact..my vaginal swab culture found enterococcus fecealis bacteria found. I've also completed the course of sensitive antibiotic linezolid for 7 days and again 14 days when similar symptoms came back. Please suggest what I should do next.. I'm in trouble
