Testing during an errand: the Jewel-Osco clinic
Because one clinic sits inside the Jewel-Osco at Ogden and Cass, a test can fit into a grocery run. Nobody in the store needs to know why you are there. In the clinic, the front desk only needs to hear that you would like testing, and everything else is discussed in a private exam room.
Urgent Care Center of Westmont, also known as Immediate Care Center of Westmont, runs both locations with a team led by board-certified physicians. Every question is asked without judgment.
Why untreated STIs matter
Read moreClose
MedlinePlus explains that many STIs cause no symptoms or only mild ones, so a person can be infected and pass it on without knowing. Some can cause serious health problems if left untreated, and women often have more severe effects. Infections can also pass to a baby during pregnancy or birth.
Untreated chlamydia and gonorrhea can lead to pelvic inflammatory disease, which can cause infertility, according to the CDC.
In rare cases, the CDC notes, untreated gonorrhea can spread to the blood or joints.
Untreated syphilis can, years later, damage the heart, blood vessels, brain and nerves.
Herpes and HIV stay in the body, but medicines can help manage them.
Testing finds these infections early. See how to test for every STD to understand what testing can and cannot cover.
