Concerns About a Possible Cold Sore in Our Five-Month-Old
Our five-month-old son, who weighs 21 pounds, has recently developed a bump above his lip. We are feeling anxious, especially since he was surrounded by many unfamiliar faces over the previous weekend. We make it a point to request that others do not kiss him, and we believe no one did during that time. Could this bump be indicative of a cold sore? Additionally, it's worth noting that he sucks his thumb, and his hand might be irritating that particular spot. Neither my husband nor I have ever experienced cold sores ourselves.

A bump above your five-month-old son's lip could be concerning, but it's understandable to feel anxious as a parent. It could be a cold sore, but there are also other possibilities like a small bump or irritation from thumb sucking. Here’s how to approach the situation:
Explanation:
Cold sores are caused by the herpes simplex virus (HSV) and can appear as blisters or sores on or around the lips. They are typically very contagious but may not be present if neither parent has experienced outbreaks. Given your son’s age and the potential for irritation from thumb sucking, this bump might also simply be a result of normal skin variations or irritation rather than a cold sore.
Next Steps:
-
Observe Closely: Monitor the bump for changes over the next few days. Look for signs such as:
- Fluid-filled blisters or crusting.
- Redness, swelling, or signs of pain.
- Any changes in your baby's behavior, like fussiness or difficulty eating.
-
Keep the Area Clean: Gently clean the area with a mild soap and water. Avoid applying any ointments or creams unless advised by a professional.
-
Prevent Further Irritation: Since your son sucks his thumb, consider providing distractions or soothing alternatives to reduce contact with the area.
-
Stay Vigilant for Symptoms: If the bump grows, develops blisters, or if he shows any symptoms like fever or discomfort, it becomes more important to seek guidance.
-
Limit Exposure: Continue to ensure that close contacts with your infant respect boundaries around kissing and touching his face to lower the risk of infections.
If you have ongoing concerns or the bump changes significantly, seeking advice from a pediatric healthcare provider can provide clarity and peace of mind.

Always prioritize your well-being, and if you feel uncertain about your exercise regimen or if specific concerns arise, consulting with a healthcare professional can be a valuable step.

Electric Shock Incident
I am a 38-year-old female, standing at 5'2" and weighing 135 pounds. Currently, I am not on any medications and have no prior medical conditions. Approximately one hour ago, while using an old electric stove, I attempted to adjust a coil to place a pan on it. As I stepped back, I heard a loud popping sound, followed by a bright flash of light that erupted between the coil and the pan. This electric spark made contact with my collarbone, causing a sharp pain and some minor abrasions on my skin. While the pain persists, there is no significant bleeding, just some superficial skin damage which appears to be healing well. I am not experiencing any chest pain. Should I be concerned about this incident? Are there specific symptoms I should monitor or actions I should take?
Seeking Insights on Recent Health Symptoms
Tomorrow, I plan to connect with some new doctors, and I'd appreciate any thoughts on the symptoms I've compiled with the help of a chatbot. I'm at a point where I want to dig deeper into potential underlying causes, as these issues have been increasing in frequency and are quite perplexing to me. **Symptoms Experienced:** • A burning sensation, tingling, and an uneasy feeling in my right hand • Consistent moisture and clamminess in the same hand • Episodes of sweating and increased heart rate while upright • Brief but sharp stabbing pain in the middle of my back, which can take me by surprise and causes me to cry out, but it fades almost immediately • Occasional trouble with swallowing • Difficulty recalling words and moments of confusion • An increased sensitivity to heat and cannabis usage • Following alcohol consumption, I sometimes encounter sudden sharp pains in my calves, more intense burning sensations, and excessive sweating, almost as if my nervous system is overreacting. These symptoms, while not debilitating and still allowing me to manage daily activities, feel distinctly unusual, leaving me with a sense of something being amiss. It's as if my body is delivering irregular or misaligned signals, particularly in my right hand. **Background Information:** In 2022, I went through a tumultuous relationship that involved several choking incidents. One of these attacks caused me to lose consciousness due to restricted blood flow in my neck, and during another, I was strangled from behind and thrown down, which left me with a vivid impression that my neck could have been severely injured. At that time, I underwent a CT scan for a ruptured eardrum but did not receive spinal imaging or a neurological assessment. The troubling symptoms didn't manifest until about a year ago, and since then, they have progressively intensified and become more intrusive in my life.
Concern Over Firm Cysts on the Penile Shaft?
At the age of 21, I've been observing the presence of two cyst-like formations on my penile shaft for the past two years. The first one is located at the top, positioned beneath the skin. It remains separate from the surrounding tissue, allowing for slight movement. It feels solid and firm, measuring around 2mm in diameter. Notably, it does not alter in size or position when I am erect, and there have been no changes in its dimensions since I first identified it. The second cyst is situated on the side of the shaft. Similar to the first, it is not attached to the skin and can also be moved slightly. This one is approximately 1mm in size and, like the first, it maintains its dimensions and placement during an erection. It has not changed in size over time either. Both cysts are characterized by their round shape, firmness, and ability to move, remaining unchanged in size and disconnected from the skin. I’m wondering about the significance of these cysts and how serious this condition might be. You can observe them when the skin is stretched, although the indentation is minimal.
Are Day 67 Results from a 4th Gen CMIA HIV Test Definitive? 23M 183cm
Following a potential exposure, I underwent testing with the 4th generation CMIA antigen/antibody examination. - Initial test conducted: 8 days post-exposure — Result: Negative (blood drawn from vein) - Follow-up test performed: 67 days post-exposure — Result: Negative (same procedure, blood drawn from vein) Both assessments were carried out at a reputable laboratory utilizing the CMIA testing methodology. I did not undergo post-exposure prophylaxis (PEP) and have not encountered any further exposures following the initial incident. Are these results sufficient to conclude that I am HIV-negative, or should I pursue additional testing? Looking for guidance on whether the results at 67 days can be deemed conclusive.
