Pelvic Inflammatory Disease (PID) affects the female reproductive system; it is a soft tissue inflection that can spread to the uterus, fallopian tubes, ovaries and the cervix. It can affect fertility and cause pain, bleeding, nausea, fever, and problems with urination, so it is very important that anyone who feels they may be affected seek medical advice as quickly as possible, as the symptoms worsen the longer the infection is present.
Doxycycline is a potent antibiotic and anti-inflammatory that is designed to treat soft tissue infections like PID, although it also works well for UTIs and STDs, fevers caused by fleas, ticks and lice and chronic infections of the eye.
