Cervicitis is an inflammation of the cervix. The cervix is the thin end of the uterus that opens into the vagina, and it may become infected or inflamed as a result of sexually transmitted infections, bacterial infections, or an allergic reaction. Symptoms of cervicitis may include a gray or yellow vaginal discharge, painful urination, and vaginal bleeding between menstrual periods. Cervicitis may also cause pain during sex and, in severe cases it may cause fever.

Cervicitis is usually diagnosed through a pelvic exam and a Pap smear. In some cases, a urinalysis may also be performed. Treatment is necessary for individuals whose cervicitis is caused by sexually transmitted infections. These individuals, as well as their partners, may require a treatment with antibiotics. Cervicitis that is caused by a sexually transmitted disease such as or chlamydia or gonorrhea, can spread to the uterine lining and the fallopian tubes, resulting in pelvic inflammatory disease, or PID. If left untreated, PID may cause fertility issues.
