Toddler's Fever Lasting Over 72 Hours: Seeking Advice
I have an 18-month-old boy in the United States experiencing a prolonged fever. Despite administering medication, which brings his temperature down for about six hours, he quickly experiences another spike. Last night, his temperature peaked at 103.2°F, followed by 103.9°F overnight. The only additional symptom he displays is a runny nose; he has been enjoying Pedialyte pops throughout the day. Last night, he also developed diarrhea. Notably, he is the only child unwell, as his 3.5-year-old sibling remains healthy. I took him to urgent care, where they confirmed that his lungs are clear and ruled out an ear infection. The medical staff advised me to consult his pediatrician if the fever persists into Tuesday, suspecting it might be viral or flu-like. They were unable to conduct a flu test due to a shortage of supplies, and results from the viral panel are expected to take 1 to 3 days. Should I manage his fever until Tuesday or seek a second opinion now? It’s important to note that he is susceptible to febrile seizures, although he hasn’t experienced any during this illness so far.

It’s understandable to be concerned when your toddler has a fever lasting over 72 hours, especially with additional symptoms like runny nose and diarrhea. Managing the symptoms while monitoring her condition is crucial.
Explanation
Fever in young children can often be a normal response to infections, including viral infections. Given that your son’s lungs are clear and there are no signs of ear infection, it sounds like you’re on the right track. The fever can be persistent, and it’s important to keep an eye on it, especially since he is prone to febrile seizures.
Next Steps
-
Continue Monitoring: Keep track of his fever, noting the temperature and any other symptoms or changes in his behavior. If he becomes lethargic, difficult to wake, or shows signs of dehydration (such as not urinating as frequently or having a dry mouth), seek immediate medical attention.
-
Manage Fever: Continue to administer fever-reducing medication like acetaminophen or ibuprofen, as directed by the healthcare provider. Ensure you're spacing doses appropriately and following the guidelines for his weight.
-
Stay Hydrated: Since he’s enjoying Pedialyte pops, continue to offer these and ensure he is drinking enough fluids to prevent dehydration. Offer water and other fluids as well.
-
Comfort Measures: Dress him in lightweight clothing and keep the room at a comfortable temperature to help with any discomfort from the fever.
-
Decision on Seeking Further Help:
- If his temperature exceeds 104°F, he seems to be in significant discomfort, or there are any new concerning symptoms (like rash, breathing difficulties, or changes in consciousness), it would be advisable to seek a second opinion or go back to urgent care before Tuesday.
- If he remains stable, you can manage his symptoms at home until you can follow up with his pediatrician based on their advice.
Being attentive to his needs while sticking with the current management plan is key. Please keep me updated if you have any concerns or notice changes!

Ongoing Low-Grade Fever Concerns
Greetings, I’m a 23-year-old male, standing at 5'7" and weighing 188 pounds. I take Adderall and do not smoke. For a number of years, I have encountered a troubling issue that is becoming increasingly frustrating. Frequently, both during the day and at night, I experience a low-grade fever ranging from 99°F to 101°F, which can persist for several hours before subsiding. When I mentioned this to my physician, he largely shrugged it off, stating that any temperature below 100.4°F doesn't count as a fever. However, I am quite fed up with feeling chilly and unwell whenever these episodes occur. Could there be alternative explanations for this condition?
High Fever and Body Pain: My Ongoing Struggle
At 24 years old, and standing at 5 feet 8 inches while weighing between 50 to 52 kilograms, I've been enduring a high fever and intense body aches for over five days without any signs of improvement. This prompted my visit to the emergency room. Upon arrival, I underwent a series of tests, including a complete blood count (CBC), CRP, and a chest X-ray in the posterior-anterior view. Fortunately, my CBC and X-ray results came back normal. However, my CRP level was alarmingly high at 43.1 mg. The doctors prescribed me cefixime at a dosage of 400 mg, along with zinc and pantoprazole. When I inquired about pain relief, the medical team assured me that I wouldn't need any, but I've opted to manage my discomfort with paracetamol, taking 650 mg extended-release three times a day. While this has successfully alleviated my fever, I still experience pervasive pain throughout my body. What are the next steps I should consider? Additionally, I was advised to return for the same tests if my condition does not improve within a week.
Expected Timeline for Thyroid Ultrasound Results
Last Friday afternoon, I underwent a thyroid ultrasound, and to my surprise, the results were available that very evening. Although I haven't received any communication from my physician, based on what I've read, it appears I may require a biopsy. I'm facing challenges in reaching the office, as my calls are directed to voicemail, and they haven't returned any calls. I'm eager to get an appointment scheduled soon, and it's causing me some anxiety. What is the usual timeframe I should anticipate between the ultrasound results being sent and my endocrinologist contacting me to arrange for a biopsy? Currently, I have four nodules, but I want to focus on the one that concerns me the most: **NODULE 1:** - **Location:** Right mid - **Size:** 1.8 cm (measured by the largest dimension only) - **Composition:** A mix of cystic and solid elements - **Echogenicity:** Hypoechoic - **Shape:** Wider than tall - **Margin:** Lobulated or irregular - **Echogenic Foci:** None with the exception of large comet-tail artifacts - **ACR TI-RADS Score:** 5 - **ACR TI-RADS Risk Category:** TR4 - Moderately Suspicious. Recommend FNA if larger than 1.5 cm; follow-up evaluations if larger than 1 cm at 1, 2, 3, and 5 years.
Accidental Overdose of Paracetamol and Naproxen: What to Do?
A 55 kg individual, around 5 feet 4 inches tall, aged 21, and a non-smoker, mistakenly consumed 6000 mg of paracetamol along with 1000 mg of naproxen within the span of one hour.

Given these circumstances, is it necessary to seek medical attention, or is the concern perhaps exaggerated by what is found online?
