What Could This Blister on My Upper Lip Be? Should I Seek Medical Advice?
I recently discovered a small blister on my upper lip, and I'm trying to figure out if it warrants a trip to the doctor. This morning, I noticed it (I’m a 23-year-old female), and it doesn’t hurt when I lightly touch it. However, applying pressure or touching it with my nails causes some discomfort (though I'm making an effort to avoid touching it altogether). Last night, I returned from an evening out with friends, but I did not engage in kissing or any intimate contact with anyone. I have no known food allergies, nor have I started any new medications. The only unfamiliar element in my routine from last night was trying a few puffs of a cigarette brand I had never smoked before. I’m not a regular smoker—I've only attempted it a handful of times in my life. I also did some quick research and learned that herpes symptoms generally appear between 2 to 20 days post-exposure, but my last sexual encounter was six weeks ago. I'm curious if anyone has an idea of what might have caused this blister, what it could possibly be, and if any action is necessary on my part. Thank you in advance for your insights!

A small blister on the upper lip can arise from several common causes, including irritation from smoking, allergic reactions, or possibly a viral infection such as herpes simplex. Given your recent smoking attempt and the lack of pain, this blister may simply be irritation.
Explanation:
- Irritation: Since you've recently smoked a new brand of cigarettes, the blister could be caused by irritation to the sensitive skin on your lips.
- Herpes Simplex: While your understanding of herpes symptoms is accurate, the timing related to your last sexual contact is significant. If it was six weeks ago, it's unlikely that this blister is due to a recent herpes infection.
- Other Causes: Blisters can also form due to sunburn, allergic reactions to products (like lip balms), or minor injuries.
Next Steps:
- Avoid Irritation: Minimize touching the blister and avoid smoking or any irritants, as this can worsen the condition.
- Apply a Soothing Agent: Consider using a moisturizing lip balm (preferably fragrance-free) to keep the area hydrated and reduce irritation.
- Monitor Symptoms: Keep an eye on the blister for any changes. If it grows, becomes painful, or shows signs of infection (like oozing or crusting), that would be a signal to seek medical advice.
- Assess Triggers: Reflect on your environment and any new products you’ve recently used that may have contributed to the blister. Discontinue any potential irritants.
- Observe Duration: If the blister persists for more than a week without improvement, consider seeking medical advice.
It's important to take care of your skin and avoid further irritation while monitoring how the blister evolves. Let me know if you have any further questions or need more support!

Should I Visit the Emergency Room?
Hello everyone! I’m a 22-year-old male, approximately 180 cm tall and weighing around 70 kg. A month back, I had a laparoscopic procedure to remove my appendix. Shortly after, within a week, I had to return to the emergency department because two of my three surgical incisions became infected. Thankfully, about three weeks ago, I received clearance and I hadn’t encountered any issues since then. For the past two weeks, I’ve been using adhesive bandages to protect the incision near my belly button, and everything seemed fine until today. Upon inspecting it, I noticed that the area looks quite inflamed and appears larger than it initially was. Additionally, it has also become quite tender. Any insights on what might be happening would be greatly appreciated. Thank you for your assistance!
Exploring Options Post-Huber Tendon Transfer Surgery
My partner, who is 35 years old, underwent Huber Tendon Transfer surgery on his left shoulder at the age of 12. This procedure aimed to address the nerve damage resulting from a traumatic delivery, during which the doctor had to forcibly extract him. Prior to the surgery, he struggled to lift his arm above waist level. Although he experienced some improvement in range of motion following the operation, it remains quite restricted; he can elevate his hand just above shoulder height, but that is the extent of his capability. The contrast between his left and right arms is a significant source of emotional distress for him. His left shoulder is noticeably smaller and hangs lower, which contributes to his feelings of frustration and dissatisfaction with its appearance. I am reaching out to discover if there are any current options available that might not have been accessible in the past. Perhaps there are orthopedic specialists who could help enhance his range of motion, allowing it to be more comparable to his right shoulder? This improvement would mean the world to him and could alleviate his disappointment regarding the functionality of his left side. I understand these details are somewhat limited, as he prefers not to discuss his condition often; however, this is the extent of what I know. I can certainly ask him further questions if it would help in finding potential solutions.
Assessing Your Risk of Contracting Mono
Recently, I spent some time with friends and received a concerning message this morning from one of them, indicating they tested positive for mononucleosis. During our gathering, I shared a couple of beverages from the same bottle with this individual; although they only took a few sips, I ended up drinking the majority of one of those drinks, which happened to be water. Given these circumstances, I’m curious about the likelihood of my contracting mono. The more I delve into the information available, the more anxious I feel. For reference, I’m a man in my twenties and engage in physical activity approximately three to four times weekly.
Inquiring About Mysterious Bumps on My Husband’s Lower Legs
Residing in central Indiana, USA, my 33-year-old husband appears to be dealing with an unusual issue. He has been experiencing what look like insect bites on his lower legs for the past two weeks. Notably, no one else in our household has developed similar symptoms, which leads us to believe he is likely encountering these while at work outside the home. The bumps have been causing him considerable itchiness, and some of these lesions occasionally exude a clear fluid for a day before forming a scab. The areas surrounding each bump do not exhibit any heat, and there is no indication of spreading redness. The discomfort remains primarily localized to the affected areas. In an effort to identify any potential causes, we have turned over the mattresses and thoroughly inspected our home for any signs of pests, yet we haven't found anything unusual. Both our children and I have remained unaffected, which adds to our confusion since he is the only one experiencing these symptoms. He has a doctor’s appointment scheduled for tomorrow, but I am seeking any insights or suggestions in the meantime. Thank you for your help!
