Concerns Regarding Oral Health
I'm a 20-year-old male who has recently become sexually active, and I’ve observed a concerning red spot on my tongue. It seems to have increased in size since yesterday. I’m looking for some guidance to determine whether this might be an STD or another issue, as I’m unable to visit a doctor at this time. Any advice would be appreciated.

It's understandable to be concerned about changes in your oral health, especially with your recent increased sexual activity. A red spot on the tongue can be due to various reasons, not all of which are related to sexually transmitted infections (STIs). Let's break this down to help you understand what might be happening and what you can do next.
Main Points
- Potential Causes: The red spot might be due to irritation, an allergic reaction, or even a minor infection. It could also be a sign of a condition like oral thrush or geographic tongue, which are not STIs.
- Observation: It's important to monitor any changes in the spot and your overall oral health.
- Self-Care Steps: There are some practical things you can do to help with the situation right now.
Explanation
A red spot on the tongue could arise from a number of non-STD related issues, such as:
- Irritation: From hot foods, sharp edges of teeth, or dental work.
- Infection: Non-STD infections like oral thrush (fungal) or a viral infection.
- Conditions: Geographic tongue, which can cause patches or spots that change in size and shape, is not harmful.
While some STIs can cause oral symptoms, they often accompany other signs such as sores or swelling in the throat. Given that your primary concern is the increased size of the spot, it is best to monitor it before jumping to conclusions.
Next Steps
- Monitor Symptoms: Keep an eye on the size and color of the spot. Track any additional symptoms such as pain, swelling, or changes in taste.
- Maintain Oral Hygiene: Brush your teeth regularly, including your tongue, and use a mild mouthwash to keep your mouth clean.
- Avoid Irritants: Steer clear of spicy or acidic foods and smoking, as these can irritate the tongue further.
- Hydrate: Drink plenty of water to keep your mouth hydrated.
- Set a Timeline: If the spot persists beyond a week, changes in appearance, or if you develop additional symptoms (like fever, difficulty swallowing, or pain), it would be beneficial to seek medical advice when possible.
If you have any concerns about STIs, consider getting tested when you're able to see a healthcare professional. Early diagnosis and treatment can help manage any health issues effectively. Let me know if you have any questions or need further support!

Unexplained Bump on Knee: Occasional Discomfort
### Overview - **Age:** 27 years - **Gender:** Male - **Current Medications:** None For quite some time, I’ve been dealing with a soft bump on my knee. My medical records indicate that this has been a persistent issue since before 2020, as noted in a doctor's entry from that year stating that I had it "for years." Although it usually goes unnoticed, I've observed that the bump tends to swell when I remain on my feet for prolonged periods, such as during extended walks or workouts. It particularly draws my attention when I transition from standing to sitting, as I can sometimes sense a slight discomfort in the area. Sudden movements like squatting can also trigger pain, especially when bending down to retrieve objects. In 2020, I sought medical advice about this issue, but on that occasion, the doctor couldn't examine the lump thoroughly because I hadn’t been on my feet long enough prior to my appointment. Based on my explanation of the symptoms, they proposed it might be a cyst. They even suggested a method to reduce it, though I have reservations about its safety, and I didn't try that approach afterward. According to the doctor's notes, they characterized it as: > Right knee: minimal ganglion noticeable primarily upon bending; not visible while standing. However, since I waited for about half an hour in the waiting area, it was less apparent at the time of examination. ### Concerns What worries me is that the bump is located near a vein, which visibly bulges when I apply pressure on the lump. This raises concerns that it could be affecting the vein itself or simply exerting unnecessary pressure. Additionally, I am troubled by the duration of the bump's presence, as it has likely been more than five years — possibly even seven — since it first appeared. ### Questions Given the circumstances, should I be alarmed by this issue? Are there available treatments, or am I fated to cope with the discomfort?

Challenges with Mobility in a Young Child
Greetings, I am reaching out in desperation for my four-year-old nephew who is experiencing difficulties with movement. He has been limping and has limited usage of one side of his body. These issues became apparent when he was just two years old. Since then, we have consulted numerous medical professionals and visited various hospitals. Unfortunately, the consensus has been that his condition is likely permanent, stemming from a problem at birth that has resulted in underdevelopment in the right hemisphere of his brain. This, in turn, affects his ability to control the left side of his body. I am turning to this broader community to seek any insights or experiences related to this condition. Is there any possibility for treatment that could restore some function? If a complete cure is not within reach, are there methods to alleviate the symptoms so he can feel more confident amongst his peers? I truly appreciate any advice or shared experiences that may guide us on this path. Thank you for your support!
Unexpected Facial Rash Near Mouth
I'm a 33-year-old female. I noticed a sudden rash near my mouth that developed yesterday. At first, it was quite painful, almost burning for several hours. Today, although it feels sore, the pain has diminished as long as I don't move my facial muscles too much. There's a strange tightness to it, as if it might crack when I try to express myself or talk. I'll share an image in the comments for reference.
Mysterious Pain in Arms and Legs
Last Wednesday, I began to experience significant discomfort in my legs. Initially, I assumed it was just muscle fatigue from my squats; however, the sensation worsened and developed into a burning pain. I noticed that the area behind my left knee was particularly sensitive when touched. Although my legs are starting to improve, I am now struggling with stiffness and swelling in my arms and wrists, making it painful to apply any pressure with my hands, and my grip strength has diminished. I have scheduled a blood test for Thursday. Could there be a reason behind these symptoms? Should I request my general practitioner to perform additional examinations? I have a young child, so the inability to function normally is significantly affecting our daily life. Thank you in advance for any insights you can provide.
