Unusual Spot Discovered on Chest
I am a 16-year-old male, weighing 158 pounds and standing at 6 feet tall. Recently, I noticed a small, odd-shaped mark on my chest that I believe appeared yesterday. I haven't experienced any injuries that could explain it. The mark is diminutive, lacks a circular form, and is asymmetrical. Additionally, there is no known family history of skin cancer. I'm just curious about what this might signify.

Noticing an unusual spot on your skin can understandably cause concern, especially given its new appearance and irregular shape. While the majority of skin marks are harmless (like moles or benign growths), changes in the skin should always be observed carefully, especially when they don't resemble typical shapes or have asymmetrical features.
Explanation:
Irregularly shaped spots on the skin can have various causes, including benign skin conditions, infections, or, less commonly, skin cancers like melanoma. Asymmetry is one of the characteristics that dermatologists often look out for when assessing moles and spots.
Next Steps:
-
Monitor the Spot:
- Keep an eye on the unusual mark for changes. Over the next few weeks, note if it changes in size, color, or shape, or if it begins to itch, bleed, or cause discomfort.
-
Document Details:
- Take a clear photo of the spot today. This will help you remember its original appearance when you check it later.
-
Practice Sun Safety:
- Protect your skin from sun exposure, as UV rays can affect all skin types. Use sunscreen daily, wear protective clothing, and avoid tanning beds.
-
Consult a Dermatologist:
- If you see changes in the spot or notice any new spots appearing, consider speaking to a dermatologist for an evaluation. They can provide a thorough assessment and reassure you about your skin health.
Remember, while many skin spots are benign, it's always better to err on the side of caution. If you have any more questions or concerns, feel free to ask!

Understanding My Heart Rate: Is It Normal?
At 17 years old, standing at 5'1" and weighing 8 stone, I'm starting to have concerns about my heart health. Recently, I've noticed irregular spikes in my heart rate, occasionally reaching as high as 180 beats per minute, even while I’m just lying in bed. Generally, when such episodes occur, both my systolic and diastolic numbers tend to increase. However, last night, my readings were 120 over 99; although 120 falls within an acceptable range, 99 is definitely on the higher side, leaving me perplexed. I don't smoke, and I drink alcohol only on rare occasions. I maintain a healthy weight and haven't had issues like this before. I previously consulted my general practitioner about these symptoms, but they reassured me that everything was likely fine and did not conduct any tests, which has left me uncertain. Should I consider making another appointment with my doctor?
Unexpected Left Chest Discomfort
Up until recently, I had never experienced any chest discomfort, but now it occurs daily, lasting anywhere from a few seconds to several minutes. The sensation is located on the left side of my chest, near the lower heart region. Surprisingly, the discomfort seems to align with my heartbeat. Strangely, when I attempt to take deep breaths or exhale forcefully, the pain intensifies. Additionally, I've observed that my heartbeat occasionally produces a ticking sound, which is concerning. For context, I am 17 years old and male, and I’m uncertain about the potential causes of these symptoms.
Concerns About My Mother's Chest X-Ray: What Should We Make of the Results?
Hello everyone! I’m reaching out to gather your opinions regarding a situation with my mother’s recent chest x-ray results. My mother, who is 55 years old, approximately 5 feet in height, weighs 53 kg, and generally enjoys good health aside from managing her hypertension, recently underwent her annual check-up. This included blood tests and a chest x-ray at a diagnostic facility. While her blood work returned all normal results, one aspect of the x-ray raised some alarms. The report included the following notes: **CHEST PA X-RAY** - Notable opacity detected in the right cardiophrenic region - Heart appears normal in size - Diaphragm and pleural recesses are intact **IMPRESSION** - A right lateral upright view is recommended for further assessment Upon presenting these findings to her internal medicine physician, there seemed to be some concern from him. He pointed out something resembling a shadow or a possible mass near the lower heart region and suggested that she should undergo a follow-up chest x-ray, and possibly a CT scan for more clarity. My mother quickly had the repeat x-ray performed at a hospital (different from the initial clinic). This x-ray only provided the imaging plate, and although the radiologist's report won’t be ready until tomorrow, my mother, feeling anxious, consulted the doctor with the new x-ray plate. He noted that the previously concerning area was now absent. He also verified that my mother did not have any symptoms such as shortness of breath or hemoptysis, to which she responded negatively. Despite the doctor’s reassurances that everything appeared to be normal on the new x-ray, we are still awaiting the formal interpretation of the results. Given this uncertainty, we would greatly value any insights or advice regarding her x-ray findings. Thank you all for your assistance!
Kitten Bite Incident: Should I Seek Immediate Care?
I adopted a kitten yesterday. She took it upon herself to gnaw on a charger, which I found rather concerning. My charming little six-week-old kitten, whom I've named Knife Face, clearly had a different opinion on the matter. In a moment of defiance, she bit my finger, leaving me with two tiny puncture wounds that bled slightly. As for myself, I am a 33-year-old woman who smokes but does not use any other substances or medications. I have not been diagnosed with any physical health conditions, although I do manage some mental health issues.
Rigid Bump Behind Ear Cartilage
I’m a 29-year-old female, and I don’t smoke or consume alcohol. My medical history is quite unremarkable, and there’s nothing significant in my family background either. Recently, I’ve discovered a hard lump positioned just behind my ear. I only notice it when I bend my ear, specifically at the cartilage area that connects to my head. It’s located at the fold and although it causes some discomfort, I would rate the pain as very mild, about a 1 on a scale of 10. This bump came to my attention around four days ago; it feels somewhat similar to bone or cartilage. As of now, I’m not experiencing any additional symptoms. Any thoughts on what this might be?
