Struggling with a Persistent Low-Grade Fever

3/3/2026, 1:20:16 AMMale25-34

I've been dealing with a frustrating low-grade fever that's really taking a toll on me. My recent temperature readings have varied between 98°F and 101.8°F on a daily basis. I've experienced occasional chills that come and go every other day, alongside a feeling of warmth that seems to strike at random times. One of my tonsils has swollen significantly, almost making contact with my uvula, which is particularly concerning. To add to my discomfort, I suffered from a headache that lasted a full 24 hours and I've been feeling stuffy lately. When I visited the doctor on January 31st, they ruled out Covid and the flu, suggesting that it likely isn’t mono either. This is despite the fact that I’ve engaged in various activities that could potentially expose me to mono, and I often feel fatigued. Their advice has been that I would feel better soon and that it's just a common cold. Unfortunately, this message hasn’t changed despite my symptoms persisting for several weeks, possibly months. My parents are uncertain about what could be causing all of these issues, but it’s worth noting that I started taking methylphenidate at a dose of 18mg right around the time my symptoms began. I'm genuinely worried about my health—it's impacting my ability to participate in sports and my academic performance is slipping. I could really use some guidance and support right now.

It sounds like you are dealing with a frustrating combination of symptoms, including a persistent low-grade fever, swollen tonsil, chills, headaches, and general fatigue. The fact that these symptoms have lasted for several weeks is understandably concerning for you.

Explanation: The fluctuation in your body temperature, together with the swollen tonsil and other symptoms, could suggest an underlying infection or inflammatory process, even if initial testing for common illnesses has ruled out conditions like COVID, flu, and mono. It's also possible that these symptoms could be tied to the initiation of methylphenidate, but this would typically be evaluated by a healthcare professional.

Prioritized Next Steps:

  1. Monitor Symptoms: Keep a detailed record of your temperature readings, symptoms, and any changes throughout the day. Note if specific activities or foods seem to worsen your symptoms. This can provide essential information if you need to revisit your doctor.

  2. Hydration & Rest: Ensure you are staying well-hydrated by drinking plenty of fluids, and try to get adequate rest. Fatigue is often exacerbated when the body is dehydrated or not well-rested.

  3. Pain Relief: Over-the-counter pain relievers such as acetaminophen or ibuprofen can help alleviate discomfort from headache and fever. Follow the dosing recommendations on the package, and consult a pharmacist if you have any questions about interactions with your current medications.

  4. Consider Environmental Factors: Evaluate your environment for allergens or irritants that might contribute to symptoms. Common culprits include dust, mold, strong scents, or smoke, which can lead to respiratory irritation and may cause stuffiness.

  5. Dietary Adjustments: Incorporate a balanced diet rich in fruits, vegetables, and lean proteins. Staying nourished supports your immune system, which is crucial when you're feeling under the weather.

  6. Follow-Up Care: Given the persistence of your symptoms, it may be beneficial to arrange a follow-up appointment with your healthcare provider, especially if the symptoms worsen, new symptoms arise, or if you have concerns about the medication you started. Be prepared to discuss your complete symptom history and any potential side effects you may be experiencing from the methylphenidate.

Stay hopeful, as many illnesses can be self-limiting and improve with time. Don’t hesitate to seek further advice from your healthcare provider if you feel your symptoms aren't improving or if you continue to feel concerned about your health. You deserve to feel better and get back to your regular activities.

What's Up with My Weed-like Odor?

At 17 years old and weighing 238 lbs, I’m a female dealing with low blood pressure, which often leads to excessive sweating. Lately, I’ve noticed that my armpits emit an odor reminiscent of marijuana whenever I’m due for a shower. Additionally, my room takes on that same distinct smell during night sweats. It’s worth mentioning that I’ve never smoked or used marijuana in any form. Is this something that happens to others as well? Is it considered normal?

Struggling with Sleep Problems and Fatigue

In early February, following a recent hospitalization, I began experiencing issues that I’m uncertain whether gradually developed or hit me all at once, but I became aware of them last month. I’ve faced difficulties with both falling asleep and maintaining it; it has been quite some time since I enjoyed a restful night. I’ve experimented with various solutions, including melatonin, magnesium, herbal teas, as well as medication such as 200 mg trazodone and 25 mg of Seroquel. Unfortunately, none of these approaches have offered me any relief. Additionally, I've looked into Cognitive Behavioral Therapy for Insomnia (CBT-I). During my first appointment regarding these sleep troubles, my doctor attributed my symptoms to "depression," but she also scheduled follow-up consultations, including a sleep study. Historically, I’ve had no issues like this, and while I’m open to the idea, I can’t shake the feeling that there might be an alternative explanation. I do not see a reason to be depressed, and I’ve noticed that these complications are starting to take a toll on me. In addition to my sleeping difficulties, I’ve been experiencing a sense of apathy, which is quite out of character for me. I feel emotionally flat and more fatigued than usual. Moreover, my sex drive seems to have completely vanished. It seems implausible that I could simply dismiss everything as "depression," especially since I was feeling fine just a month ago and have no previous history of such issues. What suggestions could I offer my doctor to help identify the potential roots of my problems?

Chronic Fatigue at 24 - Seeking Guidance

Hello, I'm feeling overwhelmed and am in search of direction regarding my health challenges. I acknowledge that any suggestions I receive are not formal medical diagnoses and I am not looking to make any drastic changes without professional advice. However, I seek any insight on what to look into or possible underlying causes of my issues. To provide some background, I have a history of several mental health disorders, including PTSD, Bipolar Disorder, ADHD, and BPD, along with an anxiety diagnosis. While my list of conditions may seem extensive, I've adhered to my medication regimen and have achieved a stable mental state after seven years of treatment. Currently, I am prescribed 300mg of Lithium and have recently added trazodone and propranolol as needed. I undergo regular blood tests every three months to monitor my lithium levels and have completed a comprehensive metabolic panel, with results indicating everything is normal. The only notable finding has been a vitamin D deficiency. Additionally, I experienced mono in 2021, but the symptoms I am experiencing have persisted since I was 14, progressively worsening over time. My primary concern is the severe fatigue I experience, which frequently leaves me unable to cope. When I stand up, I often feel a painful sensation in my chest, and on particularly challenging days, my limbs feel incredibly heavy. The discomfort is so intense that standing can bring me to tears, and it feels predominantly muscular rather than skeletal. I am frequently unwell, getting sick at least once a month, indicating a compromised immune system. After reducing my alcohol intake, I noticed the severity of my illnesses decreased, but the frequency remains unchanged. Another persistent issue is my dry eyes. Despite my doctor attributing this to insufficient blinking, I find myself drinking copious amounts of water each day. Still, I often wake up with eyes that hurt to open due to dryness. I have an ongoing craving for salt and sugars; neglecting to consume these seems to exacerbate my symptoms significantly. Even during moments of happiness, I suffer from fatigue that feels debilitating. Though I maintain a healthy weight, my ability to exercise as I once did has diminished due to the overwhelming fatigue and discomfort. Recently, I have developed unusual, itchy, scaled rashes on my skin. I regularly take my medications, but I also face irregular bowel movements and gas control issues. Most concerning is a new symptom; after consuming pork or beef, I sometimes vomit shortly after eating, which has been disconcerting. Here’s a brief timeline of my symptoms: - **Elementary School:** Monthly illness - **Middle School:** Chronic fatigue - **High School:** Increased cravings for sugar and salt - **College:** Reduced sugar and salt intake, but illness peaked, forcing me to switch to remote learning to complete my degree. - **Working:** Ongoing rashes, dry eye symptoms, digestive issues, and previous concerns persist. I maintain a balanced diet, often cooking my own meals, and drink around five to six glasses of water daily. At 5’4” and 130 pounds, I take doctor-recommended supplements. Despite working physically challenging jobs where I lift and walk regularly, I feel utterly drained and frustrated by the constant exhaustion. It feels dismissive for my symptoms to be labeled solely as mental health related. I would greatly appreciate any assistance or recommendations.

Persistent Breathlessness: Seeking Advice

Hello, everyone. I’m reaching out for help regarding a persistent breathing problem that’s starting to hinder my daily life. I experience an unrelenting urge to take a deep, fulfilling breath, yet I often struggle to find that ‘full’ sensation, leading to what feels like ‘air hunger.’ This feeling intensifies during activities such as eating, speaking, or even simple tasks like washing dishes or walking. Here’s what I’ve done so far: * **Endoscopy (EGD):** I recently underwent this procedure under general anesthesia to examine my stomach and esophagus. The results showed no major gastrointestinal problems or hiatal hernia. * **Cardiac Exams:** I had my heart examined via ECG and ECHO, and the physicians confirmed that my heart is in excellent health. * **Oxygen Levels:** I frequently monitor my oxygen saturation using a pulse oximeter, and it consistently reads at **99%**. * I also had my iron levels checked; while my iron is normal, my ferritin is low (approximately 30), though I don’t believe this is the primary issue since my oxygen saturation remains high. Additionally, I should mention: * I am **three months post-rhinoplasty**, and my nose is still quite blocked, forcing me to breathe through my mouth for over 85 days. * The onset of my breathing difficulties occurred just before the surgery, likely linked to pre-operative anxiety. There have been instances when my fear escalated to the point of seeking medical assistance, but the only response I received was a prescription for anxiety medication. Despite knowing that my breathing issues aren't life-threatening, the sensation of breathlessness persists. While I remain calm mentally and am not overtly anxious, I continue to struggle. Currently, because of nasal congestion, I am primarily mouth-breathing, but I also find myself feeling short of breath during routine activities like walking or talking, and it complicates eating as well. I would appreciate any advice or insight into this situation!
