Concern Over Enlarged Dark Spot on Finger
Hello everyone! I'm a 24-year-old male, standing at 6'2" and weighing 182 pounds. For quite some time now—possibly over a year—I have noticed a dark spot developing on my finger. The area seems to have a slightly "looser" texture, and there is reduced sensation when I compare it to the surrounding areas on my other fingers. Although it hasn’t caused any pain, I hadn’t paid much attention to it—until recently. Today, I observed that the dark spot has grown and is now extending toward my knuckle. I'm uncertain whether it's particularly noticeable or concerning, but I wanted to seek your opinions on this matter. Could it be something as simple as a fungal infection? I appreciate any feedback or advice!

It’s understandable to be concerned about changes in your skin, especially when it involves new growth or changes in texture and sensation. Based on your description, this dark spot on your finger could potentially be benign, such as a mole or a benign skin growth, but since you mentioned it has grown and changed, it’s important to take note.
Explanation
Skin changes, like enlarged dark spots, can arise from various causes, including benign conditions such as moles or lentigines (age spots), or possibly more serious issues such as skin cancer, particularly if there's a noticeable change in size, color, or texture. The reduced sensation you mentioned may indicate some underlying changes in the skin or nearby nerves that warrant further attention.
Next Steps
-
Self-Assessment: Monitor the spot attentively. Take note of its size, color, texture, and any accompanying symptoms like itching or bleeding. Document these changes over a few days.
-
Protect the Area: Ensure that you are protecting the affected finger from sun exposure and irritants, as this can affect skin health. Use sunscreen on the area when exposed to sunlight.
-
Avoid Self-Diagnosis: While fungal infections are possible, it's important not to jump to conclusions. Fungal infections typically present differently (often with flaking or scaling).
-
Seek Professional Advice: Because the spot is growing and changing, it's a strong signal to schedule an evaluation with a dermatologist. They can perform a thorough examination and may perform a biopsy if necessary for a definitive diagnosis.
-
Stay Informed: Continue educating yourself on skin health. Familiarize yourself with the ABCDEs of melanoma (Asymmetry, Border irregularity, Color variation, Diameter over 6mm, Evolving size or shape) to better understand when changes require immediate attention.
By addressing this matter promptly, you can ensure proper diagnosis and peace of mind. If you have any sudden changes like bleeding or pain, or if you feel very concerned before your scheduled visit, seek immediate care. Feel free to reach out if you have any more questions or need support!

Bump Discovered on the Back of My Head
At 28 years old, I was caught off guard when my girlfriend pointed out a noticeable bump at the back of my head. The fact that I felt no discomfort or itchiness led me to dismiss it at first. However, several hours later, my curiosity got the better of me, and I decided to snap a photo of the area. To my surprise, the bump was quite prominent. I am certain that I haven't experienced any impact to my head nor have I been bitten by anything, which adds to my confusion about its appearance.
Mass on the Top of the Mouth
A 33-year-old man, weighing 206 pounds, who is currently on an SSRI and Zepbound, has noticed a lump on the roof of his mouth that has been present for approximately one week. This lump is sensitive to the touch, with a solid feel to it.
Experiencing Nausea and Dizziness from Extended Screen Time
I am a 27-year-old woman, 5 feet tall, and weigh 140 pounds. I have astigmatism and wear corrective lenses. My occupation requires me to focus on a computer screen for 8 hours daily, and following that, I attend online classes which adds another 3 hours of screen time. After approximately 5 hours at work, I start to feel both nauseous and dizzy. While taking short walks does provide temporary relief, the symptoms return swiftly. Interestingly, this issue does not arise during my online classes—only in my work environment. This has persisted for three consecutive days. I had my glasses updated about two months ago. Are there effective strategies to alleviate this discomfort?
Discomfort Following Ejaculation
16-year-old male, weighing 140 pounds and standing at 5'9", with no health issues and limited exposure to smoking (only a few cigarillos a few months back). Occasionally after ejaculation, I experience a burning feeling that initially starts as a mild discomfort at the tip of my penis a few minutes post-ejaculation. While it begins as a mere annoyance, it quickly escalates into a sharp, stinging pain that radiates throughout my genital area, particularly at the base. I suspect this might be linked to my urethra. When I move, I feel the pain extending like a line through my perineum toward my anus. Previously, I've managed this discomfort by hovering over the toilet, sipping on plenty of water while I attempt to relieve myself. Urination seems to provide some relief; however, it often requires about thirty minutes of waiting and hydrating before I can expel it. The pain can become quite intense. I've been battling a pornography addiction and am in the process of quitting, so perhaps this is contributing to the problem, although these episodes are infrequent. I'm genuinely concerned about the seriousness of this issue and whether others have undergone similar experiences.
Was It Food Poisoning or Too Spicy?
Hello! I'm a 20-year-old female, weighing 105 pounds and standing 5 feet tall. Earlier this week on Sunday, my father prepared a chili that contained a habanero pepper along with four jalapeños for an extra kick. Normally, he is quite careful about preventing food contamination, so I didn't have any concerns. A few hours after eating, I began to experience stomach cramps, and shortly thereafter, I ended up vomiting the entire bowl of chili. After that episode, I felt an improvement in my stomach discomfort, aside from some lingering gas pain. However, I noticed that I developed a slight fever of 100.1°F. The following day, my temperature went back to normal. The stomach pain has lessened to a state of tenderness, and I've been able to keep down a Starbucks coffee and some grapes—though I realize that combining those isn't the best idea, I haven't had any adverse reactions so far. I'm reaching out because I'm eager to start eating lighter meals again, but I'm concerned that if it was indeed food poisoning, I might need to hold off for another day or two before I resume normal eating habits.
