Understanding the Blister on My Upper Lip: Should I Be Concerned?
Last night, I (F23) discovered a small blister on my upper lip. The area isn’t painful when touched lightly, but it does sting a bit if I apply pressure or use my fingernails, which I'm trying to avoid. I had just returned home from a night out with friends, and I did not engage in any romantic or intimate encounters during the evening. I don’t have any known food allergies, nor have I recently started any new medications. The only unfamiliar element in my day was trying a few puffs from a cigarette brand I hadn't smoked before (to clarify, smoking is quite rare for me; I’ve only done it maybe three times in my life). From what I’ve read, herpes symptoms may appear 2-20 days after exposure. However, my last sexual experience was six weeks ago, which makes me question the likelihood of it being related. What could be the reason behind this blister, what does it signify, and do I need to seek medical advice? Thank you in advance for your insights!

A blister on your upper lip can have various causes, and while it's understandable to feel concerned, it's important to consider the context and symptoms you're describing. Here’s a breakdown to help clarify your situation.
Possible Causes of the Blister:
-
Irritation or Allergic Reaction: The blister could be a result of irritation from something you've come in contact with, such as a cigarette, or from a change in your environment. This is often referred to as contact dermatitis.
-
Herpes Simplex Virus (HSV): While HSV can cause blisters on or around the lips (cold sores), considering your last sexual encounter was six weeks ago, it's less likely to be related if you haven't experienced any previous outbreaks. Cold sores usually recur in the same areas.
-
Other Factors: Stress, hormonal changes, or minor injuries to the lip can lead to blister formation as well.
Recommended Next Steps:
-
Avoid Irritation: Refrain from touching, picking at, or applying pressure to the blister, as this can worsen the irritation or lead to infection.
-
Keep it Clean: Gently wash the area with mild soap and water to keep it clean. Avoid using harsh products.
-
Monitor Symptoms: Observe the blister for any changes, such as increasing pain, spreading redness, or the development of other symptoms like fever. These could suggest an infection or another concern.
-
Soothing Care: Consider applying a cool, damp cloth to the area to soothe any stinging sensation. Over-the-counter topical treatments for skin irritation might be helpful if the blister is bothersome.
-
Consultation: If the blister does not improve within a few days, becomes painful, or if you develop additional symptoms (e.g., swelling, fever, or more blisters), it would be prudent to seek medical advice.
Conclusion:
Most lip blisters resolve on their own and are not usually a cause for alarm, especially if they’re not accompanied by severe symptoms. Keeping the area clean, avoiding irritants, and monitoring your symptoms are key steps. If you have further questions or notice concerning changes, feel free to reach out for more guidance. Take care!

Swelling in the Inner Lower Eyelid
A 17-year-old experienced an allergic response which resulted in redness and itchiness around the eye. In an attempt to soothe the irritation, cold water was applied and restraint was practiced. After a night’s sleep, the individual awoke to find that their pets had brushed against their face, exacerbating an allergy to pet dander. This led to a new sensation of itching in the lower inner eyelid. Upon looking in the mirror, a slight pouch was observed, which became more pronounced when squinting. Although it didn’t appear red or excessively itchy, it felt smooth and had a sensation of fullness. What could this indicate, and what are the potential risks associated with it?
Inquiries About Smoking and Lung Cancer Risks
Hello, physicians, I wanted to share a bit about my background: I am a 27-year-old male who smoked for a total of five years, specifically from 2020 to 2022 and then again from 2024 to 2025. I quit yesterday. Back in April 2025, I had a consultation with a pulmonologist where I underwent a pulmonary function test (PFT) and an X-ray. Both results came back normal, as confirmed by the doctor, though I unfortunately cannot provide the report here. I have a few questions: 1. Based on my smoking history of approximately 3 to 5 cigarettes per day for five years, am I at risk of developing lung cancer? 2. Is it necessary for me to get a low-dose CT scan for cancer screening? 3. Since I quit smoking shortly after my visit to the pulmonologist, should I consider repeating the pulmonary function test? I tend to have a bit of obsessive-compulsive behavior, which is why I’m reaching out with these concerns.

Exploring Private Healthcare Options Alongside NHS Services in England
I recently underwent an NHS ultrasound, which revealed a new and painful 14mm lesion on my spleen. The entire experience has left me feeling exceedingly frustrated, particularly due to the slow response and the seeming reluctance of my GP's office to pursue more thorough investigations. Despite my concerns about this rapidly developing lesion, there appears to be hesitation in moving forward with additional scans or assessments to pinpoint the underlying cause. Should I pursue a detailed scan through a private provider and receive a definitive diagnosis or at least clearer insights into the nature and origin of this lesion, would it be possible to present these findings to my GP and request that they take immediate action? While I am not in a position to fully transition to private healthcare, I am open to utilizing it strategically to encourage my GP to address my medical needs more effectively.
What's Included in Your Recovery Routine?
Hello! I'm a 30-year-old male standing at 5'9". Over the past year, I've been fine-tuning my recovery regimen and I've come to understand that it's much more comprehensive than simply incorporating stretching and protein supplements.
