Is the Red Line Linked to a Pimple on My Shoulder?
F22, Weight: 200 pounds Is it common for a pimple to exhibit a red line extending from it? I have been experiencing acne on my shoulder frequently. Recently, I discovered a pimple on my shoulder. It feels warm when I touch it and seems to create a lump beneath the skin’s surface. Although it's not painful and doesn’t irritate me, I’m still a bit concerned. After I fiddled with it, I noticed a red line starting to appear from the area surrounding the pimple. The shape isn’t uniform; it looks rather blotchy instead of a perfect circle. I’m feeling okay overall, but I did spend considerable time outdoors today. Interestingly, the red line doesn’t appear to align with any veins or patterns I recognize.

It’s understandable to be concerned about a pimple associated with a red line, especially with the description of warmth and a lump beneath the skin. The red line could indicate localized inflammation or infection, but let’s break this down.
Main Points:
- The red line may signal inflammation or infection.
- Pimples can sometimes become more complicated if irritated or manipulated.
- Regularly monitoring the situation is essential.
Explanation:
When a pimple feels warm and has a lump beneath the surface, and especially when accompanied by a red line, it could be a sign of a few things, such as:
- Folliculitis (inflammation of the hair follicle) or an infected pimple.
- The red line itself might indicate irritation or an infection spreading from the pimple. Often, red lines can denote that the body is reacting to something—like an inflammation response.
Since you mentioned that you spent considerable time outdoors, sometimes exposure to heat and sun can exacerbate skin conditions or make existing issues more noticeable.
Next Steps:
-
Keep the area clean: Gently wash the area with mild soap and water to prevent any further irritation or infection. Avoid using harsh products.
-
Avoid picking or squeezing: It’s essential to let the pimple heal naturally to prevent worsening any potential irritation or infection.
-
Monitor the symptoms: Over the next few days, keep an eye on the pimple. If the red line worsens, the area becomes more painful, or if you develop a fever, it would be essential to reassess the situation.
-
Consider applying a cold compress: If there’s discomfort or the area feels inflamed, a clean, cold compress may help reduce inflammation.
-
Track any changes: Note if the pimple increases in size, changes color, or if any new symptoms arise.
If you don’t see improvement within a week or if your condition worsens, consider seeking professional evaluation for tailored treatment. Remember, it’s always good to err on the side of caution with skin concerns.

Concerns Regarding Ciprofloxacin/Dexamethasone Ear Drops
Hello, I am a London resident, M42 175, with no known allergies, ongoing medications, or health concerns. For the past four days, I've been experiencing a blockage in my left ear, accompanied by discomfort. I suspect this is due to a combination of earwax accumulation and inflammation from swimming at the beach during my recent vacation. While I haven't had any fever or discharge, there's noticeable pain whenever I rest on my left side or eat. I consulted a general practitioner who prescribed me Ciprofloxacin and dexamethasone ear drops. To my surprise, my research online revealed several alarming side effects associated with this medication. I found information not only on various Reddit discussions but also from official government websites, which raised some serious concerns: https://www.gov.uk/drug-safety-update/fluoroquinolone-antibiotics-new-restrictions-and-precautions-for-use-due-to-very-rare-reports-of-disabling-and-potentially-long-lasting-or-irreversible-side-effects I'm questioning how this prescription was deemed appropriate for my condition. Are there any safer alternatives to these ear drops that I could consider? Thank you!
Concerns Over Multiple Medications Prescribed to Boyfriend
My boyfriend, a 26-year-old male, standing at 6 feet 1 inch and weighing 202 pounds, has recently been given a range of prescriptions including prednisone, levofloxacin, nasal azelastine, and nasal fluticasone. For more than two months, he has struggled with a stuffy nose, a nasally voice, a persistent cough, and has recently developed a runny nose along with an aggravated cough. After undergoing a 10-day antibiotic regimen, he found little relief. Subsequently, about a month later, he received two different nasal sprays, which unfortunately seemed to exacerbate his mucus problems. What concerns me is the absence of any CT or X-ray imaging in his evaluation. I’m wondering whether it is standard practice to prescribe such antibiotics and corticosteroids based solely on a tentative diagnosis of "acute sinusitis." I am worried about the potential side effects associated with these medications. Thank you in advance for any insights you can provide.
Options for Kidney Failure Treatment Without Insurance
My brother, who is in his forties, has recently received a dire prognosis—he's been told he has only sixty days left to live. His kidneys have ceased to function, and according to his nephrologist, there are no further treatment options available. Due to his history of alcoholism, he does not qualify for a transplant, and it seems he’s also not considered suitable for dialysis, although the reasons for this are unclear to me. This situation has left my mother in a profound state of sadness, especially since he is the father of three young children, all of whom are now without a maternal figure. I find myself wondering if it would be feasible to acquire a dialysis machine and provide it to him, should I have the financial means. I am aware that his home would require adaptations for water supply and electrical connections, and he would need some training to operate the machine. Alternatively, is it possible for me to directly pay for his treatment at a medical facility? If I can handle the costs, are there any legal or ethical barriers preventing me from financing a way to extend his life? I have noticed that second-hand dialysis machines are listed online for under $5,000, which raises significant questions for me. Why is he facing death when a relatively small sum of money could potentially prolong his life? It feels absurd to me that my nephews might have to endure the loss of their father over such a manageable expense. I can't help but feel that there must be a crucial detail I am overlooking in this frustrating scenario.
Understanding Non-Diabetic High Anion Gap
I am a 27-year-old individual, standing at 5 feet 9 inches and weighing 210 pounds. Health Concerns: I have been diagnosed with hyperlipidemia and multi-level cervical spondylosis, with a possibility of lumbar and thoracic stenosis. However, neurology specialists have opted not to proceed with further orders, as my assessments do not point to myelopathy. In my past, I actively participated in marathons and cycling. Unfortunately, I've been dealing with various health issues that have remained undiagnosed for several years. My symptoms include dizziness, difficulty breathing, heart palpitations, and an abnormal lipid profile, among other health concerns. Though I can provide a detailed list of test results if needed, I'll summarize my situation for brevity. In December 2023, while training for marathons, I experienced significant fluctuations in my heart rate, even during rest. This sparked a journey to uncover the reasons behind these changes and to assess whether I was genuinely as healthy as my lifestyle suggested. I have consulted with cardiology, neurology, neurosurgery, and urology specialists. Although findings like hyperlipidemia and multi-level cervical stenosis have offered some clarity, I continue to seek answers. Currently, I have noticed that my anion gap is elevated, sitting at 15.9, despite not being a diabetic. Due to the various symptoms mentioned earlier, I haven’t been able to maintain my usual workout routine, but I try to engage in light activities, such as zone 2 cycling and walking, whenever possible. My A1C level is reported at 5.6. I would greatly appreciate any guidance on this matter. If you require more detailed information or additional test results, feel free to ask; I am happy to share further details.
Strange Bumps Beneath the Skin
Hello, I apologize if my English isn't perfect. I’d like to share my experience for some clarity: I underwent a surgical procedure in my groin area. The doctors referred to my condition as a furuncle and carbuncle. Since the operation a little over three weeks ago, I've recently begun to feel pain in my thigh. The discomfort is significant, affecting about half of my thigh, and if I apply pressure, I can detect a bump that seems to measure around 2 to 3 cm in size. It feels firm, though not excessively so. I'm quite concerned about this pain as it has made walking difficult for me.
