Genital herpes is the most common sexually transmitted infection that causes buttock pain. The herpes simplex virus (type 2 in most cases) lives in nerve clusters near the base of the spine, and when it reactivates, it can send shooting or tingling pain into the buttocks, hips, and legs, sometimes without any visible sores. Chlamydia can also cause lower back pain that radiates to the buttocks, though this is less common and typically linked to a deeper pelvic infection.
Why Herpes Causes Buttock Pain
After the initial infection, the herpes simplex virus settles into nerve cells in the sacral ganglia, a cluster of nerves at the base of your spine. The virus stays dormant there between outbreaks. When it reactivates, it travels along those same nerve roots, which branch out to the genitals, buttocks, hips, and upper legs. This is why herpes can produce pain in areas that seem unrelated to a genital infection.
The nerve involvement can cause a condition called sacral radiculopathy. In plain terms, the virus irritates the nerve roots in your lower spine, producing radiating pain, numbness, tingling, or even temporary weakness in the legs. Some people also experience urinary retention or constipation during flare-ups because the same nerve bundle controls bladder and bowel function.
What Prodromal Pain Feels Like
Many people with herpes experience warning signs hours or days before visible blisters appear. These prodromal symptoms often include tingling or shooting pain in the legs, hips, or buttocks along with genital discomfort. The pain can feel like a deep ache, a burning sensation, or sudden electric jolts down one leg. If you notice a recurring pattern of buttock pain followed by an outbreak, that connection is characteristic of herpes.
Recurrent outbreaks tend to be shorter and less severe than the first episode. Over time, most people find that flare-ups become less frequent, though the prodromal nerve pain may persist as one of the more noticeable symptoms even as visible sores become milder.
Buttock Pain Without Visible Sores
One of the trickier aspects of herpes is that it can cause nerve pain in the buttocks without producing obvious blisters. Some people experience recurring burning or tenderness on the lower back or buttocks and assume it’s a skin condition or muscle issue. If a sore in the buttock area doesn’t heal with standard treatment for common causes like fungal infections or pressure irritation, herpes should be considered.
The virus can also shed from the genital area during a buttock flare-up even when no genital lesions are present. This means the infection can still be transmitted sexually during episodes that seem limited to the buttocks. Globally, over 520 million people between ages 15 and 49 are living with genital HSV-2, and a significant portion don’t know they carry it because their symptoms are mild or atypical.
How Chlamydia Can Cause Lower Back and Buttock Pain
Chlamydia doesn’t typically cause buttock pain on its own, but it can if the infection spreads. In women, untreated chlamydia can lead to pelvic inflammatory disease, which produces deep lower back pain that may radiate into the buttocks. In men, a chlamydia infection in the rectum (from receptive anal sex) can cause rectal pain and discomfort that extends to the surrounding area. Lower back pain is listed among chlamydia’s possible symptoms, though it usually signals the infection has progressed beyond its earliest stage.
Gonorrhea behaves similarly. A rectal gonorrhea infection can cause pain, discharge, and soreness in the anal and buttock region. Both chlamydia and gonorrhea in the rectum are often asymptomatic, so pain in this area after unprotected anal sex warrants testing even if symptoms are mild.
Getting Tested
The type of test depends on what’s suspected. For herpes, a swab of an active sore gives the most reliable result. If no sores are present, a type-specific blood test can detect antibodies to HSV-1 and HSV-2, though it can’t pinpoint where on the body the virus is active. Blood tests are most accurate at least 12 weeks after potential exposure, since antibodies take time to develop.
For chlamydia and gonorrhea, nucleic acid amplification testing (a highly sensitive molecular test) is the preferred method. If you’ve had receptive anal sex, a rectal swab is necessary, since a standard urine test won’t detect infections at that site. These tests can return results within a few days.
Treatment and Managing Nerve Pain
Herpes is managed with antiviral medications. A first outbreak is typically treated with a 7 to 10 day course of antivirals, which shortens the duration and severity of symptoms. For people who get frequent recurrences, daily suppressive therapy (taking a lower dose every day) reduces the number of outbreaks and lowers the risk of transmitting the virus to partners. Episodic therapy, where you start medication at the first sign of prodromal symptoms, is another option. Starting treatment early, ideally as soon as you feel that familiar tingling or buttock pain, makes episodic therapy most effective.
For nerve pain specifically, some people find that the antiviral alone is enough to quiet the burning and shooting sensations. Others with more persistent radiculopathy may need additional approaches for nerve pain management, which a healthcare provider can tailor to the severity and frequency of symptoms.
Chlamydia and gonorrhea are both curable with antibiotics. Once treated, the buttock or lower back pain they caused typically resolves within days to weeks, depending on how far the infection had spread before treatment began.
