Can Seromycin Control Symptoms Of A Runny Nose And Lethargy?

I am 42 yr old with bartholin cyst first time and has been there for a few months now. All stds and other bacterial cultures show nega tive. No abnormal bleeding - had ultrasound - told 3 complex cysts lke attached to each other... no biopsy or antiobiotics given - i had a surgery in november and haven't felt good since. i have felt like i'm fighting an infection - i ended up with bronchitis and given, antiobiotics. To this day i still have nose running, lethagic feeling, tired even after night's sleep. I wanted to try an antibiotic (seromycin) in hopes it would work. Could this even be a lymph node?
