Unexplained Red Spots on My Skin
At 16 years old, I recently discovered some unusual red spots on my body, particularly on my neck, the right side of my chest, and my thigh. My mom brought them to my attention yesterday. These red patches resemble either a rash or signs of an allergic reaction; however, they don’t come with any sensations like itching, burning, or peeling. They appear as flat yet slightly raised dots and areas of redness. I do shave my legs, but that doesn’t seem to account for the spots appearing on my neck and chest, as I don’t shave those areas. For some time now, I’ve been supplementing with vitamin D due to previously low levels, but I’ve never encountered these red marks before. I have an appointment with both a dermatologist and my doctor tomorrow. I feel anxious to get to the bottom of this and learn how to treat it. A friend’s birthday party is scheduled for the 16th, and I want to ensure whatever this condition is, it isn’t contagious or prone to lingering.

It's understandable to feel anxious about the unexplained red spots on your skin, especially with an upcoming event like your friend's birthday party. Here's a summary of the main points regarding your situation, plus steps you can take.
Main Points
- The red spots may be caused by various factors, including irritation, skin condition, or an allergic reaction, but they don't appear to be contagious.
- Your skincare routine and recent vitamin D supplementation will be relevant for the dermatologist’s evaluation.
- Monitoring the spots and your skin condition leading up to your appointment will be beneficial.
Explanation
Red spots on the skin can have numerous causes, ranging from benign conditions like a heat rash, to potential allergic reactions, or even a mild infection. The fact that these spots are not accompanied by itching, burning, or peeling is reassuring, as it often indicates less irritation. The different locations of the spots suggest they may not all be related, especially since you don’t shave the areas on your neck and chest. It’s good that you’re seeing a dermatologist and your doctor, as they can provide a more definitive diagnosis.
Next Steps
-
Observe: Before your appointment, note any changes. Do the spots fade or change color throughout the day? Are there any new spots? Keeping a record of their appearance will be helpful for your doctors.
-
Avoid Irritants: Stay away from new soaps, lotions, or laundry detergents until you have more information. This helps rule out irritation or allergic reactions.
-
Gentle Skin Care: Use mild soap and avoid scrubbing the affected areas. Moisturizing with a fragrance-free lotion may help soothe any irritation.
-
Preparations for the Appointment: Think about any new products you've used recently, changes in your diet, or other symptoms you might have overlooked. Having this information ready will assist your healthcare providers in making an accurate diagnosis.
-
Stay Relaxed: Trust that your doctors can help you find the answers you need. Most skin conditions are manageable, and many are temporary. You should be able to enjoy your friend’s birthday party without concerns of contagion.
Your proactive approach to your health is commendable, and I hope your doctors will provide clarity and a resolution soon! If the spots change or new symptoms develop after your appointment, keep monitoring and add this information to discuss with your doctors.

Concerns About Morning Heart Rate Drops
A 30-year-old female, previously a smoker and abstaining from drugs and alcohol, seeks advice about a troubling situation regarding her heart rate. She has a history of various health conditions, including Hypermobile Type Ehlers-Danlos Syndrome, suspected Postural Orthostatic Tachycardia Syndrome (POTS), tachycardia, fibromyalgia, venous insufficiency, deep vein thrombosis (DVT), and superficial clotting, but no genetic clotting disorders have been identified. Currently, her medication regimen consists of: - In the morning: Metoprolol 12.5mg, Vyvanse 30mg, and Eliquis 5mg. - Midday and evening: Recently initiated low-dose Naltrexone, currently at 4.5mg. - At bedtime: Clonazepam 1mg and another dose of Eliquis 5mg. Since beginning the low-dose Naltrexone, she has experienced significant drops in her heart rate during the morning hours, sometimes falling to the low 50s and even the 40s. These episodes only occur shortly after waking, around 7-9am, with the most recent drop reported at 9am, where her heart rate plummeted to 35 beats per minute prior to taking her morning Metoprolol. During these episodes, she has experienced fleeting face tingling that dissipates within a few minutes. Throughout the remainder of the day, her heart rate fluctuates between 55 and 130 beats per minute, with these morning drops being a notable exception. She is grappling with whether this alarming drop in heart rate warrants a visit to the emergency room. Although she suspects this may seem trivial to some, her past experiences at the hospital have left her feeling hesitant, as her conditions are sometimes not taken seriously. She has attempted to reach her primary care physician for guidance but has not yet received a response. According to her pain management doctor, the Naltrexone is not likely to be the cause of her heart rate issues. With her complex medical history and the distressing symptoms she is experiencing, she is seeking advice on whether an emergency room visit is needed for further evaluation of her heart rate concerns, despite her reservations about being dismissed by medical professionals again.

Experiencing Mild Reactions to Bactrim Post-Surgery – Is It Safe to Continue?
Hello everyone, I'm seeking some guidance on a situation I've encountered. I am a 35-year-old assigned female at birth (AFAB) and have struggled with chronic skin conditions such as eczema for over five years. Recently, I underwent pelvic surgery, and during a subsequent check-up, my physician conducted a swab that identified a few bacteria, including E. coli. As a result, I was prescribed both metronidazole and Bactrim, which I have been taking for several days now. Shortly after starting the medications, I experienced some minor itching at a site of eczema, which subsided fairly quickly. However, I’ve noticed the development of raised, itchy bumps on my face soon after my latest dose. These bumps did not expand and disappeared within a few hours. Alongside this, I also experienced a general sensation of itchiness and tingling across my scalp and forehead. Given that I have a known allergy to another frequently prescribed antibiotic, my doctor expressed hope that I could continue with Bactrim. I was advised to keep taking it unless my symptoms worsened and to use antihistamines to alleviate the itchiness, provided it does not progress to hives. I’m trying to remain calm about this, but I’m uncertain about whether these symptoms might worsen or if they are just mild irritations. I would greatly appreciate any thoughts or advice. Is it common to manage mild reactions like this, or are there typically safer alternatives that would effectively address the situation?
Jaw Discomfort and Sore Throat Concerns
A 30-year-old female with a background of thyroid cancer is currently prescribed levothyroxine and labetalol. Lately, I've been experiencing discomfort beneath my jaw and adjacent to my ear. Thankfully, my ear is unaffected and free of infection. I’ve visited urgent care a few times for this issue and now plan to consult with a dentist. My oral hygiene is quite good; I regularly floss and care for my teeth diligently. I have never engaged in smoking or vaping. I suspect the source of this discomfort might be linked to a wisdom tooth extraction I underwent approximately 13 years ago, though I’m uncertain. I'm feeling unwell but doubt it's related to a viral infection or strep throat. Still, I’m unsure about the cause. Should I be worried?
