Concerns Over Red Marks on Arms and Legs
Hello, I'm a 40-year-old woman who's been dealing with long COVID for the past year. While my heart is currently being evaluated, I've noticed two red marks appearing—one on my arm and another on my leg. The mark on my arm emerged after a workout, which is unusual for me. I’m curious about what these might indicate. The arm mark seems like a flattened area that’s gradually fading after two days, while the leg mark, which appeared more recently, has a slight elevation. Is there any cause for alarm here? I’m worried this might be a sign of serious vascular issues stemming from my long COVID experience. Any advice would be greatly appreciated. 😞

It's understandable to be concerned about new symptoms, especially in the context of long COVID. The red marks you've described can arise from various benign causes, but it’s wise to monitor them given your health history. Here’s an overview of possible explanations and some clear next steps you can take.
Main Points:
-
Possible Causes of Red Marks: The flattened red mark on your arm could be due to a variety of factors including exercise-induced irritation, a minor rash, or even a small bruise. The elevated mark on your leg may indicate an insect bite, small bump, or allergic reaction, but it might also be a sign of inflammation.
-
Long COVID Considerations: While you’re right to be cautious because of your long COVID history, most skin changes like these are not typically markers for serious vascular issues.
Explanation:
- Flattened Area: This could be a post-exercise response where increased blood flow causes slight redness or a bruise from minor trauma.
- Slightly Elevated Mark: This might be a localized response to an irritant, an insect bite, or even an allergenic reaction to something you've come in contact with.
- Association with Long COVID: While long COVID can involve various symptoms, skin manifestations like these are less likely directly linked to serious vascular problems, unless accompanied by other concerning symptoms like significant swelling, warmth, or pain.
Next Steps:
-
Monitor Changes: Keep an eye on both marks. Note if they change in size, color, elevation, or if you develop any additional symptoms such as pain, warmth, swelling, or systemic signs like fever.
-
Self-Care Measures:
- Apply a Cool Compress: This can help soothe any irritation or itching.
- Keep the Area Clean: Practice good hygiene to prevent any potential irritation or infection.
-
Document Symptoms: Keep a journal of your symptoms including any new marks, how long they last, and any associated symptoms. This will aid in communication with a healthcare provider if needed.
-
Seek Medical Attention: If the marks do not improve within a few days or if they worsen (e.g., if you experience new symptoms like swelling or pain), it’s essential to reach out to a healthcare provider for further evaluation.
Your concern is valid, but many skin changes can resolve on their own or with minor self-care. Stay observant, and don’t hesitate to prioritize your health by getting checked if things do not improve. You're taking a responsible approach by being proactive about your health!

Am I Too Late?
24F Greetings, I'm using a temporary account for privacy. I've been caught up in a persistent worry about a possible pregnancy and I'm seeking some clarity. I had unprotected intercourse on August 13, 2024, and here we are on June 22, 2025 — over 10 months have gone by. If that encounter had led to a pregnancy, would I have already given birth by this time? I’m not looking for advice on symptoms or pregnancy tests — my main concern is understanding from a biological perspective whether it’s feasible that I could still be expecting at this point. Can I safely conclude that I am in the clear? I really appreciate any considerate feedback. This situation has been quite taxing on my mental state.
Seeking Insights on a Persistent Rash: Update and Test Results
I've revised this post to incorporate some crucial information. I am aware that Reddit isn't a platform for medical diagnosis. I've already visited urgent care and scheduled a meeting with my primary care provider in hopes of being referred to a rheumatologist, but my appointment isn’t until August. In the meantime, I find myself in a state of worry and uncertainty. The urgent care physician prescribed me Triamcinolone and advised that I see a rheumatologist as urgently as possible. However, the Triamcinolone hasn’t alleviated the itching at all. I am reaching out to see if anyone has had experiences similar to mine that led to diagnoses such as lupus, rheumatoid arthritis, or lymphoma. What might be happening with my body? During my urgent care visit, the staff mentioned that any of these three conditions could be possibilities, but they suggested starting with a rheumatologist for my skin issues. A little about me: I am a 27-year-old female, 5'3" tall, weighing 144 lbs, not currently on any medication, and I have been smoking cigarettes and marijuana for approximately 12 years. About two months ago, I developed an intensely itchy rash located on the back of my neck. It sometimes feels like it’s burning. I haven't changed any of my soaps, products, or detergents lately. None of the lotions, cortisone creams, or allergy medications have provided relief. My history with skin issues is minimal, aside from some polymorphic light eruption that developed in recent years, but no eczema. I've noticed swelling in the lymph nodes at the back and sides of my neck, as well as behind my ears. I have previously experienced hard, swollen lymph nodes, particularly on the left side of my neck, for about five years now. The swelling in the back of my neck's lymph nodes appeared after the onset of the rash. The area is incredibly itchy, occasionally burns, and feels warm to the touch. I now have open sores in the rash area that are refusing to heal. Additionally, I feel itching on the skin covering my lymph nodes, even in areas without any rash. Before I let the internet convince me that a minor rash could indicate something severe like lymphoma, I wanted to seek opinions here. In a follow-up note, I realized I also neglected to mention that a couple of months before this neck rash surfaced, I started experiencing circular, occasionally itchy patches on my legs and stomach, along with one on my foot. These new spots seemed to have a similar pattern, not healing or disappearing over time, and they itch, though not nearly as intensely as the rash on my neck. I've also observed several of these spots on my legs, three on my stomach, and one on my foot from the initial set of images I mentioned earlier. To make things clearer, I have included an update of my most recent CBC from October 2024, which was noted as abnormal. Additionally, my Basic Metabolic Panel taken on the same date showed abnormalities, along with elevated D-dimer levels and visibly swollen lymph nodes in my neck. For the past couple of years, I've been struggling with swollen lymph nodes, feelings of malaise, fatigue, and various other health issues, losing around 100 pounds in a non-deliberate manner. I'm increasingly worried that I might be facing some type of slow-growing lymphoma. My appetite has significantly declined; when I do feel hungry, I have a very brief window to eat before the urge diminishes. Often, I can only manage one meal a day, if I’m fortunate enough to have the appetite to eat at all. It’s worth noting that I've also dealt with polymorphic light eruption each summer for the past three to four years, which only appears on my arms. I have tested negative for HIV, Lyme disease, and my ANA is normal (below 1.8). My rheumatoid factor is <10, thyroid levels are 1.20 mcIU/mL, and my sedimentation rate is 13. My comprehensive metabolic panel has indicated trace protein in my urine, which sometimes appears foamy. I had a bout of mono in my teenage years about a decade ago, accompanied by exceedingly high levels of the Epstein-Barr Virus.
Concerns About Potential Parasites
I apologize for bringing up an uncomfortable topic, but I need some insight. I'm a 34-year-old woman, weighing around 195 pounds and standing at 5 feet 5 inches. For years, I've experienced symptoms indicative of IBS or IBD, although I've never received a formal diagnosis. Occasionally, I notice unusual stools that contain what look like white thread-like substances. I've tried various over-the-counter anti-parasitic medications and even underwent stool testing a few months back, but results were unremarkable. Lately, I've been feeling unwell, battling a persistent cough and experiencing fever for several days. I'm gradually improving, but now I'm confronted with these peculiar signs. What could be going on with my health?
Could This Have Been Sepsis?
Hello, everyone! I’m reaching out out of pure curiosity regarding an incident that transpired over ten years ago. I'd love to hear your thoughts on it, if it's not too much trouble. At the time, I was a 19-year-old woman, standing at 162 cm and weighing between 50 to 55 kg. I wasn't on any consistent medications. Initially, I began to notice flu-like symptoms; however, it didn’t quite match what I typically associated with the flu. On a Saturday, I made an appointment with my general practitioner. As the nurse exited the lab, she urgently instructed me, "You need to go to the emergency room immediately!" Following her advice, I headed to the hospital, where I was administered antibiotics. In the days that followed, I found myself feeling immensely fatigued to the point of forgetting to eat, and I struggled to communicate effectively. Additionally, I developed itchy bumps on my skin, which I attributed to mosquito bites since it was summertime. The following week, I woke up feeling itchy all over. I thought it was still those pesky mosquitoes. But as I scratched, the rash expanded rapidly until my entire body seemed to be affected. I began to experience difficulty breathing as my throat started to constrict. I returned to the hospital—this time it was a Sunday and my doctor’s office was closed. I was gasping for air and received an emergency injection. Afterwards, I was kept in the dermatology unit for an entire week, during which going outside was not permitted. What’s unnerving is that the medical staff were unable to diagnose my condition. They referred me to a specialized clinic for allergy testing, but the results showed that I had no allergies. While hospitalized, I experienced significant swelling in my hands along with various rashes across my body. These were distinct from the earlier itchy bumps, presenting only as redness and swelling. I would greatly appreciate any insights you might have as to what this experience could potentially indicate. Thank you!
Seeking Answers for an Unexplained Skin Condition
I’ve come back to share some additional information regarding my situation. I acknowledge that Reddit isn’t a platform for diagnosis, yet I've already visited an urgent care center and scheduled an appointment with my primary care physician, hoping to secure a referral to see a rheumatologist. Unfortunately, my appointment with the PCP isn’t until August, leaving me in a state of anxiety and uncertainty. During my urgent care visit, I was given Triamcinolone to alleviate the itching, but it hasn’t provided any relief. I’m a 27-year-old woman, standing at 5’3” and weighing 144 pounds. I do not take any medications and have a long history of smoking both cigarettes and marijuana for approximately 12 years. About two months ago, I developed an intensely itchy rash localized to the back of my neck. It occasionally feels like it’s burning, but I haven’t changed any of my personal care products, detergents, or soaps. Over-the-counter lotions, cortisone creams, and allergy medications have proven ineffective. My medical history includes the occasional polymorphic light eruption (PMLE), but no problems akin to eczema or other skin conditions prior to this. Additionally, I have swollen lymph nodes in the back and sides of my neck, as well as behind my ears. This is not a new occurrence for me; I’ve dealt with hard, swollen lymph nodes, including one on the left side of my neck that I first noticed about five years ago. The swelling in the neck nodes appeared after the rash developed. The rash is extremely uncomfortable, producing a burning sensation and considerable heat to the touch. I’ve also noticed several open sores forming in the rash area that seem unwilling to heal. Interestingly, my lymph nodes are itchy too, particularly the skin over them, even in areas without rashes. Before jumping to health conclusions based on Internet searches, I thought it wise to ask for insight from the Reddit community. Edit 1: In addition to the neck rash, a couple of months prior, I began noticing some circular, occasionally itchy patches on my legs and stomach, with one also appearing on my foot. These spots are persistent and do not seem to heal. Edit 2: I've documented several of these patches on my legs, three on my stomach, and one on my foot. Edit 3: I’ve included my most recent complete blood count (CBC) from October 2024, which indicated abnormal results. Edit 4: A basic metabolic panel from October 24 also showed abnormalities, including elevated D-dimer levels and a visibly swollen lymph node in my neck right now. Over the past couple of years, I’ve been plagued by swollen lymph nodes, fatigue, a general feeling of malaise, and a range of other health issues, all accompanied by an unintentional weight loss of about 100 pounds over this period. I am deeply concerned about the possibility of a slow-growing lymphoma. My appetite has diminished significantly; when I do feel hungry, it’s for a very brief window during which I must consume food quickly before the urge disappears again. On a fortunate day, I can manage to eat only once daily. Additionally, I have experienced polymorphic light eruption each summer for the last three to four years, but only on my arms. I have tested negative for HIV and had mono as a teenager, about ten years ago, which resulted in notably high levels of the Epstein-Barr virus at that time.
