Seeking Advice on My Toddler’s Rash
Hello, parents! I’m reaching out to get your insights on a skin condition affecting my 18-month-old daughter. Here’s a timeline of what has happened: On Wednesday, she developed small red spots (see first image), which unfortunately worsened by Thursday after she took Claritin (second image). By Friday morning, despite four doses of Benadryl and two doses of prednisone, the condition showed no signs of improvement (third image). However, by Friday night, we finally began to notice some progress. I’m curious to hear your thoughts on what this rash could be. A bit of background on my little girl: she’s a 27-pound toddler with no known drug allergies, and she has a history of recurrent ear infections and experienced moderate to severe croup at 9 months old. She is fully vaccinated and stays at home with no exposure to daycare. Notably, her older siblings, who are all under five, are not experiencing any illness. The rash first appeared after her nap on Wednesday, starting on her extremities and face. There haven’t been any recent changes regarding soap, lotion, or medications. The only new item she consumed in the last day was juice that contained guava. Interestingly, she doesn’t seem to be bothered by itching. This rash has developed following a week of having a runny nose but without any fever. A virtual consultation with a pediatrician suggested it might be a post-viral rash, advising me to administer an antihistamine. I had already been giving her daily doses of Zyrtec for her runny nose, with no other symptoms present. Within 12 hours, the rash spread to her torso and neck but did not cause her any breathing difficulties or lesions in her mouth. The diaper area appeared clear, and her bowel movements remained unchanged. Concerned about the spreading nature of the rash, we visited urgent care on Thursday. By then, it had transitioned from distinct spots to larger diffuse areas, although it didn’t resemble the raised hives my other children have had in the past. During this visit, they discovered she had an ear infection and prescribed antibiotics and steroids for her conditions. It’s worth mentioning that she has previously received penicillin and cephalosporin antibiotics four times, the last occurrence being five months ago, so I'm not particularly worried about a penicillin allergy. Her last vaccinations were six months ago. On Friday morning, the appearance of the rash remained relatively unchanged, with only a slight spread to the torso and face. Upon repeating doses of Benadryl and steroids, as well as giving her a bath without any soap to rule out contact allergens, we still saw no improvement after 24 hours of treatment. Finally, by Friday evening, I was relieved to see that the rash had started to settle down — the redness and warmth diminished and the spots reverted to their original state from Wednesday afternoon. What could this be? I appreciate any insights or similar experiences you might have had!

It sounds like you're understandably concerned about your daughter's rash, especially given its progression and the treatments you've undertaken. Based on your detailed timeline and the absence of other concerning symptoms, it seems she may be experiencing a post-viral rash, particularly following her recent runny nose.
Explanation
Post-viral rashes are not uncommon in young children, especially after mild viral infections that don't cause significant illness. They often appear days to weeks after the viral symptoms start and can change in appearance, similar to what you described. The fact that there was no itching and no involvement in the diaper area is reassuring. The progression of the rash you described, along with the start of treatment, suggests her body is responding to whatever is causing the rash.
Since she is now showing signs of improvement and you followed the pediatrician’s advice, that’s a positive sign. The introduction of new food (the juice with guava) could have contributed as well, but given your description, it seems more likely related to her recent viral illness or the response to the medications.
Next Steps
-
Continue Monitoring: Keep a close eye on the rash. If it continues to improve over the next few days, this indicates recovery.
-
Hydrate Well: Ensure she stays well-hydrated, especially if she has any additional mild symptoms like a runny nose.
-
Avoid New Products: Stick with her usual skin and bath products for now, as you’ve done, to rule out any potential contact allergens.
-
Document Changes: Take notes on any changes in her symptoms or any new rashes that may appear as you've done. This will help if you need to discuss it with another healthcare provider in the future.
-
Consult a Pediatrician if Needed: If the rash worsens, or if new symptoms arise (e.g., fever, increased irritability, or changes in her behavior), consult with her pediatrician for further evaluation.
Your approach thus far has been thorough, and it's great that you are proactive. Always trust your instincts as a parent—if you're ever in doubt, don't hesitate to seek professional advice. Keep up the good work caring for her!

24M | Unexplained Fainting Incident
**Note:** I previously shared this story, but it was inexplicably removed. I’m a 24-year-old male without any medical diagnosis or prescription medications. While I do consume alcohol occasionally, I hadn’t been drinking before this happened. Around 3 a.m., I got up from bed to use the restroom. As soon as I began to urinate, I suddenly felt a wave of dizziness. The next moment I was aware of was regaining consciousness in the bathtub, startled awake by the sensation of something dripping on me—only to discover it was my own blood. This was my first experience with fainting. When I came to, confusion set in. I was disoriented and couldn’t comprehend why I was being dripped on while in what I thought was my “bed.” Strangely, I also imagined that I was lying on a collection of marbles (which I actually don’t own)—this turned out to be the shattered glass of my shower door lying around me. I’m uncertain whether I lost consciousness first and then fell, or if the fall caused my brief blackout. It took me a few moments to understand why I was in the bathroom at all. I’m not sure how long I was out; I only remember it was around 3 in the morning when I initially got up, and about the same time when I regained consciousness. I dialed 911, and the ambulance arrived promptly. They checked my vitals, performed an EKG and measured my blood sugar, finding nothing unusual. At the emergency room, they repeated the vital checks, conducted a CT scan, drew blood, and took x-rays—yet still no abnormalities were detected. I had several cuts on my face and left arm (curiously, this is the arm that would have been turned away from the door), along with bruising around my ribs. Since the incident, I’ve been suffering from headaches and pain in my ribs. I received stitches on both my face and arm. The nurse suggested I could have stronger pain relief, but I opted for just Toradol. They eventually discharged me, stating, "We’re unsure what caused this, but return if it happens again." What might have triggered such an incident? How can I safeguard against it reoccurring if they remain uncertain about the cause?
Healing Progress Post-GBS: Toe Concerns
I am a 28-year-old male, measuring 5 feet 10 inches and weighing 131 pounds. My current medications include Fomadatine and Zyrtec, prescribed due to my ongoing battle with Chronic Gastritis and SIBO. I maintain a healthy lifestyle, abstaining from both smoking and alcohol. My health concern revolves around the toe adjacent to my pinky toe on my left foot, as well as my pinky toe on the right foot. Since August of last year, I have been on the mend from Guillain Barre Syndrome. Recently, I've noticed that at night, the skin on my feet tends to turn a reddish pink, although this usually improves after I walk around. However, two of my toes have remained red, with one appearing slightly swollen. Generally, my pinky toes are quite thick, but the condition of my left foot's toe is worrisome for me. It seems that I'm unable to upload an image to illustrate my issue.
Swelling Beneath My Chin Near the Jawline
18-Year-Old Male: I'm reaching out to any medical professionals who might provide insights into my situation. I've been using marijuana since I was 14, but now, at 17, I'm making an effort to stop and have been clean for 18 days. Recently, I've discovered an unusual swelling located just beneath my chin, behind my jaw. It causes some discomfort when I move, yet it doesn’t feel painful continuously. I'm somewhat anxious that this could be indicative of a more serious issue, especially considering it's positioned near my chin's lymph nodes. Any advice or information would be greatly appreciated as it might help alleviate my worry.
Challenges with Appetite and Discomfort While Eating — Difficulty in Gaining Weight
As an 18-year-old male, I find that I become satisfied after consuming rather minimal amounts of food. This situation presents a considerable challenge, particularly since I only need to have a standard breakfast, lunch, or dinner to feel completely satiated for the remainder of the day. My goal of increasing my weight has made this issue even more complicated. When I limit myself to one meal per day, I often face weight loss or an uncomfortable sensation of fullness that leaves me feeling sluggish. Opting for two meals makes me feel excessively bloated, distracting me from my daily responsibilities. Moreover, I suffer from an unusual issue with my throat, where almost any food I consume causes discomfort, as detailed in the list below. I have contemplated focusing on having just lunch while continuing my weightlifting regimen to maintain my current weight and gradually build muscle. What advice could you offer? Could there be an underlying cause for these symptoms? Lastly, would it be wise for me to consult a healthcare professional? Foods That Cause Discomfort: Bread, flour, pizza, fruits, sugary or starchy items, seed oils, chips, and essentially everything else. Foods That Are Tolerable: Rice, salads, chicken, fish, and vegetables. Overall Symptoms Include: * Quick satiety after normal meals * Challenges in gaining weight * Bloated and lethargic sensations when consuming more than one meal * Persistent throat sensitivity to a wide variety of foods
Seeking Insights: My Journey with Undiagnosed Neurological Symptoms
Hello everyone, I'm a 34-year-old female grappling with neurological symptoms that first appeared in October, and I’m eager to hear from anyone who might have faced similar challenges. My journey began with unexpected migraines, blurred vision, and an ongoing sensation of being off-balance or intoxicated. Gradually, I began experiencing mainly sensory-related symptoms, such as tingling and burning sensations, feelings of extreme heat and cold, sharp pains radiating in my arms and back, as well as discomfort in my hands and toes, alongside intermittent numbness. I also endure varying degrees of weakness and heaviness in my right side, specifically my arm and leg, although I haven’t suffered complete functional loss. The nature of my symptoms is erratic; they fluctuate rather than consistently deteriorate. An MRI revealed mild, scattered lesions in the white matter, which were deemed nonspecific. Further tests from a lumbar puncture returned normal results, showing no markers of inflammation, and the oligoclonal bands were not present. A thorough range of lab tests yielded no significant findings. After evaluating my case, the neurology team suggested a possible diagnosis of MS and administered a three-day course of intravenous steroids. While I noticed a slight improvement in some sensory pain, my symptoms persist and continue to vary day by day. I still experience headaches and pressure in my head along with episodes of blurred vision, but there have been no new deficits since treatment. I am reaching out to connect with others who have had similar experiences. I would like to learn about the insights or diagnoses you encountered and what treatments proved beneficial (such as those related to migraine disorders, dysautonomia, or sensory neuropathy, for example). If you have navigated a similar path, I would greatly appreciate your sharing your story. Thank you!
