Symptoms: Could It Be HIV or Allergies?

Is it a symptom of HIV?

On September 4th, I noticed many red rashes on my body that initially itched.
When I scratched them, they appeared more prominently.
The next night, one or two new bumps developed, with two of them forming raised blisters in the groin area and on my arm, which burst the following day.
After a few days, I felt hot and sweaty, particularly around my neck at night, although my bed was dry.
I also observed a 0.5 cm red rash on the glans.
There are many mosquitoes at home, and I am easily bitten, but I'm unsure if that is the cause.

On September 11th, I visited a doctor who drew blood for testing and performed a rapid dengue fever test, which returned negative.
The doctor prescribed medication to reduce fever and treat staphylococcus and other yeast infections.
After a few days, the rashes gradually improved and faded to brown spots.
Concerned about HIV, I underwent a saliva screening, which also came back negative.
Occasionally, my body feels sore, with pain lasting for a day or two.

On September 25th, I fell while skateboarding and twisted my ankle, but it was a minor injury.
My tongue had a white coating.
From September 25th to 26th, I experienced occasional dizziness, possibly due to recent academic stress, which resolved after my coursework ended.
On September 25th, I noticed small raised spots under the corona of the glans, which did not spread and were slightly itchy.
Currently, it is stable, not spreading, and not itchy.
I underwent another saliva screening on September 24th, which was also negative.

From May to September, I had occasional unprotected sexual encounters with men.
On September 25th, I had an allergic reaction after eating shrimp, and the previous rash locations reappeared.
I have a history of drug allergies and atopic dermatitis.

More Info

When considering the symptoms you've described, it is essential to differentiate between potential causes, including HIV infection and allergic reactions. The symptoms you've experienced, such as the appearance of red rashes, itching, and localized swelling, can be indicative of various conditions, including allergic reactions, infections, or even the acute phase of HIV.

Understanding Symptoms
1. Rashes and Itching: The red rashes and itching you noted could be due to several factors. Allergic reactions to food, medications, or environmental allergens (like insect bites) are common causes of such symptoms. The fact that you mentioned an increase in mosquito activity at home could suggest that some of your symptoms might be related to insect bites, which can cause localized swelling and itching.

2. Localized Swelling and Blisters: The development of water-filled blisters that eventually burst could indicate a viral infection, such as herpes simplex, or a severe allergic reaction. In the context of HIV, while skin rashes can occur, they are typically accompanied by other systemic symptoms, such as fever, fatigue, and swollen lymph nodes.

3. Fever and Sweating: The episodes of feeling hot and sweating, particularly at night, can be associated with various conditions. In the case of HIV, these symptoms may occur during the acute infection phase, which typically presents 2-4 weeks after exposure. However, they can also be related to infections or other illnesses.

4. Oral Symptoms: The white coating on your tongue could suggest oral thrush, which is common in immunocompromised individuals, including those with HIV. However, it can also occur due to other factors, such as antibiotic use or oral hygiene issues.

5. Physical Symptoms: The body aches and feelings of dizziness you experienced could be attributed to stress, anxiety, or even minor infections. Stress can significantly impact your physical health, leading to symptoms like fatigue and dizziness.

HIV Considerations
Given your history of unprotected sexual encounters, it is prudent to consider the possibility of HIV. The acute HIV infection phase can present with flu-like symptoms, including fever, fatigue, and rashes. However, the absence of other common symptoms, such as swollen lymph nodes or persistent fever, may reduce the likelihood of acute HIV infection.

Testing and Diagnosis
You mentioned undergoing saliva tests for HIV, which can be a reliable screening method. However, it is crucial to understand that the window period for HIV testing can vary. While some tests can detect HIV antibodies within 1-2 weeks, others may take longer. Therefore, if you suspect exposure, it is advisable to follow up with a healthcare provider for a comprehensive evaluation, including a blood test for HIV, which is more definitive.

Conclusion
In summary, while your symptoms could potentially align with acute HIV infection, they are also consistent with allergic reactions or other infections. Given your history of unprotected sexual encounters and the presence of concerning symptoms, it is essential to continue monitoring your health and seek further medical evaluation. A healthcare provider can offer more tailored advice, including additional testing and treatment options. Remember, early detection and intervention are key in managing any potential health issues effectively.
