Dr. Ji Zhaoyun reply Otolaryngology

Hello, based on your description, it is most likely that you are experiencing pharyngitis and oral ulcers accompanied by cervical lymphadenopathy.
Treatment typically involves the use of certain medications, and antibiotics may be prescribed if necessary.
However, if the cervical swelling continues to progress and leads to a deep neck infection, it is essential to take antibiotics and other medications.
It seems that there are multiple small sores in your mouth, which could be ulcers.
Most ulcers heal within two weeks of treatment, but if they persist beyond two weeks, further examination is required.
Your current condition appears to lean towards pharyngitis and oral ulcers with cervical lymphadenopathy.
If the condition is still progressing, it is advisable to consult an otolaryngologist and take medications as needed.
Wishing you safety and health.
Sincerely, Dr.
Chi Chao-Yun, Head of the Department of Otolaryngology, Taichung Hospital, Ministry of Health and Welfare.

When it comes to concerns about HIV transmission and symptoms following oral sex, it's important to understand the nature of HIV, its transmission routes, and the timeline of symptoms.
HIV (Human Immunodeficiency Virus) is primarily transmitted through three main routes: unprotected sexual intercourse (anal, vaginal, or oral), sharing needles with an infected person, and from mother to child during childbirth or breastfeeding. Oral sex is considered a lower-risk activity for HIV transmission compared to anal or vaginal intercourse, but it is not risk-free, especially if there are cuts or sores in the mouth or if the partner is HIV positive.

In your case, experiencing swollen lymph nodes two days after oral sex raises questions about the cause. While HIV can cause swollen lymph nodes, it typically does not manifest this quickly after exposure. The acute HIV infection phase, which can include symptoms like fever, fatigue, and swollen lymph nodes, usually occurs 2 to 4 weeks after exposure, not just two days. Therefore, it is unlikely that your swollen lymph nodes are a direct result of HIV infection from the encounter you described.

Swollen lymph nodes can be caused by various factors, including viral infections (like the common cold or flu), bacterial infections, or even localized infections in the mouth or throat. It's also possible that anxiety and stress about the encounter could contribute to physical symptoms, including lymph node swelling.

If you are concerned about HIV or other sexually transmitted infections (STIs), it is advisable to get tested. Testing for HIV is recommended at least 2-4 weeks after potential exposure, with follow-up testing at 3 months to confirm results, as this is within the window period for accurate detection of the virus.
Additionally, if you experience other symptoms such as fever, sore throat, or rash, it would be wise to consult a healthcare provider. They can evaluate your symptoms, provide appropriate tests, and offer guidance on any necessary treatment or preventive measures.

In summary, while swollen lymph nodes can be concerning, they are not a definitive indicator of HIV infection, especially so soon after the encounter. It is essential to seek medical advice for proper evaluation and testing to address your concerns and ensure your health and well-being.
