What Could These Skin Marks Be?
User Information: 34-year-old male, standing at 5 feet 8 inches with no previous history of dermatological issues. Recently, I detected some unusual marks on my lower back. They are causing some itching, yet there’s no pain associated with them. The texture is smooth, but they protrude somewhat above the skin surface. I noticed a small, pinpoint-like feature within one of the marks, which I’ve unfortunately scratched a bit too much. I am not experiencing any fever, feelings of nausea, or pain at the moment. Upon waking this morning, I observed that the size of the marks appears to have increased, as shown in another picture I took. Additionally, I discovered two similar marks on my shoulder today; they resemble the ones on my back. It’s been roughly two days since I first noticed these changes. Initially, I suspected bed bugs; however, I wash my bedding bi-weekly, and I don’t typically sleep without a shirt. I appreciate any insights you may have!

Your recent skin marks and accompanying itching may have several explanations, such as an allergic reaction, insect bites, or a dermatological condition. It's good that you’re monitoring the symptoms closely, and I understand that any new skin changes can be concerning.
Explanation:
The smooth texture of the marks, along with the itching, suggests they could be related to an allergic response or contact dermatitis, especially since you also noted a small pinpoint feature within one of them. It’s also possible that they could be dermatological conditions such as hives, fungal infections, or even a mild form of eczema. Since you mentioned that scratching has occurred, this can sometimes worsen the appearance and size of skin marks as well.
Next Steps:
-
Avoid Scratching: To prevent irritation and potential infection, try to avoid scratching the affected areas. You may use a cold compress to alleviate itching if needed.
-
Monitor Changes: Keep an eye on the marks for the next few days. Document their size, color, and any new symptoms. If they continue to grow, become painful, or if you notice signs of infection (like pus or increased redness), this may require further attention.
-
Skin Care: Consider applying a gentle, hypoallergenic moisturizer or anti-itch cream (like hydrocortisone) to soothe the affected areas, but avoid heavy ointments that could trap moisture and worsen the problem.
-
Evaluate Surroundings: Since you ruled out bed bugs, also check for any new products (like soaps, detergents, or lotions) that you may have started using recently, which could be causing an allergic reaction.
-
Protect Yourself: If you are exposed to potential allergens (like pets or outdoor pollen), consider creating a barrier, like wearing long sleeves or using a mild antihistamine, until you determine the cause of the reaction.
If the situation does not improve over the next week or worsens, consider seeking further evaluation. Stay observant and take care of your skin! Let me know if you have any additional questions or need further information.

Seeking Clarity After Recent Symptoms: Is a Second Opinion Justified?
Hello everyone, I’m new to the forum and could use some advice regarding my health situation. Over the past weekend, I experienced what I suspect might have been a transient ischemic attack (TIA), but unfortunately, my physician seems doubtful about this due to my age (I’m 26). I've had intermittent blood pressure issues for several years, previously managed with medication in 2022-2023, which was linked to lifestyle and stress factors. Additionally, there is a significant family history of heart-related problems, including heart attacks and hypertension. I've suffered from migraines since childhood and have been under daily medication for over a decade, which is the only medication I currently take. On Saturday, my day began normally until the afternoon when I suddenly developed a severe headache located at the crown of my head, accompanied by tunnel vision. Shortly thereafter, I experienced intense neck pain that progressively stiffened so much that I could barely move my head. During this episode, I also struggled with speech, feeling as if I couldn’t articulate what I wanted to say. My blood pressure surged to 197/93 at that point. Thankfully, the most intense symptoms subsided within 5 to 10 minutes, though the headache and neck stiffness lingered for an hour. While I considered heading to the emergency room, the rapid relief of symptoms made me hesitate. Eventually, my blood pressure decreased to 177/88 and then further to 156/84. Since that incident, I’ve been dealing with noticeable weakness on my right side, including a feeling of potential leg buckling and diminished strength in my arm and grip. I’ve also been extremely fatigued and have had occasional episodes of mental fog and difficulty finding my words, often stuttering—a new experience for me. I still don’t feel like my usual self. I managed to get an urgent appointment with my primary care physician the next day, but he appeared rather skeptical, claiming it’s unlikely that someone of my age would encounter a TIA, despite my symptoms fitting the profile. My blood pressure upon arrival was still high at 154/90. He confirmed the right side weakness using basic examinations and ordered a brain MRI and blood tests "for precaution," although I’ve been led to believe that a TIA typically wouldn’t be visible through an MRI. My doctor suggested that what I experienced was more likely an anxiety attack or a complicated migraine, which doesn’t resonate with me as I had no anxiety triggers before this episode and I do not have an anxiety disorder. Additionally, my extensive history of migraines contradicts this explanation, as none of the symptoms matched anything I’ve encountered in the past. After receiving the MRI results indicating no issues, my doctor seems inclined to dismiss my concerns, attributing everything to anxiety—something I strongly disagree with. I genuinely think I should seek the insight of a neurologist, and possibly a cardiologist, considering my family history. Am I justified in feeling dismissed in this situation? Is obtaining a second opinion a reasonable course of action? Talking to my wife about this, she also seems to think I may be overreacting, which adds to my feeling of isolation. Another layer of frustration is the financial burden of these medical appointments and imaging, which has not been inexpensive, especially given my current economic situation. Thank you for any thoughts or guidance you can offer!
Caring for a Split Nail
A 32-year-old woman, weighing 130 pounds and standing at 5'6" tall, recently discovered that one of her nails has suffered a horizontal break halfway through. The fractured area feels elevated and tender to the touch. To address the situation, she has already cleaned the split with soap and water, having noticed some dirt lodged within the crack. What measures can she take to safeguard against infection developing beneath the nail?
Insights on Mesh-free Hernia Surgery: My Journey with Infection and Healing
On August 11th, I underwent surgery for my umbilical hernia without the use of mesh. Regrettably, shortly after the procedure, I developed an infection at the incision site. Now, two weeks have passed, and I found it necessary to return to the hospital for treatment with intravenous antibiotics. Given that it's been over two weeks since the surgery, I'm left wondering if this infection is standard or if it signifies something more troubling. I'm particularly concerned since my wife is eight months pregnant, and I had hoped to be in good shape before our baby's arrival.
Seeking Guidance After Nine Months of Unexplained Neurological Symptoms
At 27 years old and weighing 210 pounds, I find myself in a prolonged struggle with an array of perplexing neurological issues, entering my ninth month without any definitive diagnosis or relief. My predicament began after a routine dental appointment for fillings where I suddenly experienced a wave of disorientation. Since that day, I have grappled with numerous troubling symptoms such as odd sensory experiences, involuntary movements, and severe sleep disturbances. Currently, I'm unable to engage in work or daily activities, frequently plagued by overwhelming feelings of dread that strike unexpectedly. My cognitive clarity has diminished significantly, causing me to feel rather lost. Unfortunately, attempts at treatment have been largely futile. I have tried various medications including clonazepam, lamotrigine, oxcarbazepine, clonidine, gabapentin, and multiple rounds of antibiotics in hopes of addressing a potential underlying infection. My prescription history also includes several courses of steroids, though I am beginning to consider antipsychotic medications after a couple of weeks. Despite undergoing MRI and CT scans that yielded normal results, the initial diagnosis of Temporal Lobe Epilepsy has since been discarded, leaving me without a current label to my condition. The sensation I experience is akin to existing in a constant liminal space—never truly awake yet never fully asleep—immersed in a half-dream state. An odd disparity between my left and right sides has emerged; the left side feels almost numbed or sedated, while the right side maintains a sense of normalcy, even though my strength is evenly matched on both sides. With this overwhelming reality, I find myself at a crossroads, unsure of the next steps to take. My symptoms have rendered my existence unbearable, and I feel increasingly distant from discovering any effective treatment method. Efforts to alleviate discomfort with sedatives or anxiety-reducing options have often intensified the perceptual distortions, leading me to prefer the anxiety instead. If anyone has advice or recommendations, I would greatly appreciate your insight.
