Oral sores can indeed be concerning, especially when they persist and show signs of worsening, such as increasing size or pus formation. While there are many potential causes for oral sores, including canker sores, herpes simplex virus infections, or even allergic reactions, sexually transmitted infections (STIs) can also manifest as oral lesions.
In your case, the development of sores in the mouth that appear to be worsening after several days of home treatment raises a few important considerations. First, it is essential to differentiate between various types of oral lesions. For instance, canker sores are typically painful but do not usually present with pus. In contrast, sores caused by herpes simplex virus can appear as blisters that may rupture and ooze, often accompanied by pain and discomfort.

If you have engaged in oral sexual activities, there is a possibility that the sores could be related to an STI, such as oral herpes (caused by HSV-1 or HSV-2) or syphilis, which can also present with oral lesions. Other STIs, like gonorrhea or chlamydia, can also infect the throat and lead to symptoms that might include sore throat and lesions, although these are less common.

Given that your sores have not improved with over-the-counter treatments and are instead worsening, it is crucial to seek medical attention. A healthcare provider can perform a thorough examination of your oral cavity and may recommend specific tests, such as a swab of the sore for viral culture or PCR testing, to determine the exact cause of the lesions.
In addition to the physical examination, your healthcare provider will likely ask about your medical history, including any recent sexual activities, symptoms of other STIs, and any other health issues you may have. This information is vital for accurate diagnosis and treatment.

If the sores are indeed caused by an STI, treatment options vary depending on the specific infection. For example, antiviral medications are effective for herpes simplex virus infections, while bacterial STIs may require antibiotics.
In the meantime, it is advisable to maintain good oral hygiene, avoid irritating substances (such as spicy or acidic foods), and refrain from any activities that could further irritate the sores. Over-the-counter pain relief medications may help alleviate discomfort.

In summary, while oral sores can arise from various causes, including STIs, the persistence and worsening of your symptoms warrant a professional evaluation. Prompt medical attention will not only help in diagnosing the underlying issue but also in providing appropriate treatment to facilitate healing and prevent further complications. Please do not hesitate to reach out to a healthcare provider as soon as possible for a comprehensive assessment.
