28M Curious About Lip Bump

7/30/2025, 7:50:20 AMMale25-34

As of July 30th, just after midnight, I've discovered a small protrusion on my lip, which initially appeared on the morning of July 29th. This bump resembles a blister. I returned from a brief trip to Canada on July 28th, but I'm unable to pinpoint what might have caused this issue. I don't smoke and I’m generally in good health, so I'm puzzled about the origin of this bump.

The small protrusion on your lip could be a blister, which may arise from several causes, including viral infections (like cold sores), minor trauma (like biting your lip), allergic reactions, or even irritation from products you used. Given that it’s recent and you’ve traveled, consider these factors as potential triggers.

  1. Viral Infections: If the bump is indeed a blister and you're experiencing any tingling or burning sensation, it might be related to the herpes simplex virus (cold sore), which is common and can be triggered by stress or sun exposure.

  2. Trauma: Sometimes, lip bumps result from accidental biting or friction, especially if you've eaten something irritating or changed your diet recently.

  3. Allergic Reaction: Exposure to allergenic substances (like certain foods, cosmetics, or environmental factors) could result in localized lip swelling.

Next Steps:

  1. Observe the Bump: Monitor the bump for any changes over the next few days. Check if it increases in size, if it's painful, or if there are signs of infection like redness or pus.

  2. Manage Symptoms:

    • If you feel discomfort, consider applying a cold compress to the area to reduce swelling and soothe irritation.
    • You may also use over-the-counter topical treatments specifically for blisters or healing ointments like aloe vera or zinc oxide.
  3. Avoid Irritants: Be cautious with lip products, foods, or activities that might have triggered this bump. Try to minimize contact with potential irritants or allergens.

  4. Stay Hydrated: Drink plenty of water and maintain good oral hygiene to promote healing.

  5. Watch for Symptoms: If you develop fever, significant pain, or new bumps appear, or if the bump doesn’t improve within a week, consider seeking further evaluation.

Feel reassured that many causes of lip bumps are minor and often resolve on their own, but keeping track of any changes is essential to ensure proper care. Let me know if you have further questions or need additional information!

Could This Be Eczema?

The subject in question is an 11-year-old boy who presents with a persistent itchy, red rash accompanied by inflammation and small bumps. Two pediatric specialists have diagnosed him with eczema. This condition seems to worsen during the winter months. In contrast, during the other seasons, the affected area appears rough and shows slight hyperpigmentation, but it remains free of redness and inflammation, and there are no symptoms during this time. Various treatments, including hydrocortisone, Duoderm, and Eucerin eczema lotion, have proven ineffective against the rash. For today, I have received a delivery from Amazon that includes Gold Bond medicated eczema relief lotion, white cotton gloves, and a non-soap hand cleanser. He is very particular about washing his hands after every restroom visit. I would appreciate your input and advice on whether I am on the right track with the treatment plan. Thank you for your assistance.

Is It Possible to Develop Allergies in Adulthood?

The concept of developing allergies later in life has been on my mind. A young woman I know, who is 22 years old, had no issues being near cats in her childhood. However, as she matured, she started exhibiting allergic reactions. Additionally, she used to enjoy strawberries without any problems, but recently she experienced swelling in her mouth after consuming a handful of them. To give you a bit of context, she stands at about 156 centimeters tall and weighs around 50 kilograms. It's noteworthy that she doesn't partake in alcohol, smoking, or any recreational drugs.

Unexplained Urticaria Episodes

A 28-year-old woman, measuring 158 cm and weighing 72 kg, has been experiencing episodes of urticaria for the past month without any obvious cause. The issue began following a localized reaction to her migraine treatment, particularly the medication erenumab. Generally, she has minor reactions to this injection; however, the last two doses have led to significant flare-ups. Subsequently, she began to notice hives appearing sporadically, primarily without identifiable triggers. These episodes tend to intensify during the night but usually subside after taking cetirizine, an antihistamine. Additionally, she has known drug allergies to ciprofloxacin and penicillin. Recently, after taking cefpodoxime, she developed a rash within a few hours, although cefixime did not provoke any adverse reactions.

Rash on the Dorsal Side of My Hands

A 24-year-old male, standing 5'3" and weighing 125 pounds, is not currently taking any medications. While I do not smoke, I am often exposed to secondhand smoke from those around me, and I have recently spent time in an environment where a significant amount of unpleasant smoke is produced due to casting activities. For approximately three weeks, I have been experiencing a rash on the backs of both my hands. I initially became aware of it after working on my car's engine. The rash has led to dryness and itching, and I took a photo after my shower today, highlighting the redness that has become particularly noticeable. What are some effective treatments for this condition?

Understanding Foam in Urine: When is it a Concern?

Age 24, I've observed a notable increase in the amount of foam in my urine over the past couple of years, compared to what I remember from before. About a year ago, I mentioned this to my primary care physician, who seemed somewhat dismissive of my concerns. Nonetheless, they proceeded to conduct a urinalysis, which returned normal results, indicating no elevated protein levels. I frequently undergo blood tests, and both my eGFR and creatinine levels typically fall within the normal range, although I did experience some fluctuations linked to a bout of mononucleosis a couple of years back, where my eGFR dipped near 70; it currently remains above 100. I suspect that changes in my urological function, likely from aging, are contributing to a stronger urine stream now than in my youth. The foam generally settles down after a few minutes, although occasionally it lingers longer than expected. I make a concerted effort to stay hydrated, even though I don’t always succeed, so I wonder if mild dehydration could partially account for the foaming. This concern is particularly relevant as I'm resuming strength training and planning to increase my protein consumption. I want to ensure that my kidneys are not overtaxed due to any potential underlying issues. Additionally, I have a history of taking 5 grams of creatine daily, paired with plenty of water, which makes me cautious about this, too. Is there a point at which foaming in urine is considered excessive, or does a specific threshold exist that I should be aware of?
