Understanding Persistent Symptoms: A Case of Possible EBV
A 17-year-old female has been experiencing a high fever ranging from 101 to 103 degrees Fahrenheit, accompanied by a severe sore throat, widespread body aches, fatigue, and noticeable weakness over the span of six days. Vomiting episodes on days four and five necessitated a visit to the emergency department, where she was treated with steroids and received two bags of intravenous fluids. Testing for COVID-19, influenza, strep throat via PCR, and RSV returned negative on three separate occasions since the second day of illness. Blood work indicated a white blood cell count of 19,000. The emergency department noted the presence of significantly enlarged tonsils and suggested a diagnosis leaning towards mononucleosis. Post-discharge lab results revealed the following: a positive EBV VCA IgG level at 77.3, a negative IgM result of less than 10, and a notable positive for EBNA-1 Antibody IgG at 306. However, tests for EBV EA and strep culture were not conducted. Even now, the patient’s tonsils remain large and exhibit white patches. This young woman has had similar symptoms of fever, sore throat, body aches, and fatigue, with multiple negative tests for flu, RSV, strep, and COVID-19 at least five times over the last eight months. What alternative diagnoses could we consider, or what further inquiries should we make? Should we request antibiotics or additional tests?

Your concern regarding the ongoing symptoms in this young woman, particularly after multiple tests and a diagnosis leaning towards mononucleosis, is valid. While Epstein-Barr virus (EBV) infection is a likely culprit, particularly given the positive VCA IgG, there are a few important considerations and potential next steps.
Summary:
- The patient presents with persistent symptoms consistent with EBV-related illness or another underlying issue.
- She exhibits significant tonsillar enlargement with white patches, fatigue, and elevated white blood cell count.
- Continuing symptoms after multiple negative tests suggest further evaluation is warranted.
Explanation:
EBV is a common virus that can lead to infectious mononucleosis, with symptoms like fever, sore throat, and fatigue. The positive IgG antibodies indicate past infection, but the negative IgM suggests this may not be a current acute infection. It's also worth noting that symptoms can persist for some time after the acute phase. However, given the recurrent nature of her illness over the past several months, we should consider alternative diagnoses and further investigations to rule out other conditions.
Recommended Next Steps:
-
Monitor Symptoms: Keep track of any changes in symptoms, especially increased severity or new symptoms like breathing difficulties, severe headache, or rash.
-
Consider Additional Testing:
- Throat Culture and EBV EA Testing: This helps evaluate for any bacterial infections that may require antibiotics and further assess the status of EBV.
- Heterophile Antibody Test: This test (often known as the Monospot test) can help confirm current or past EBV infection.
- Complete Blood Count (CBC) with Differential: This can provide additional insights regarding the immune response and rule out other conditions.
-
Assess for Other Conditions: Persistent fatigue and recurrent symptoms could point towards conditions like:
- Chronic Fatigue Syndrome (CFS): Characterized by extreme fatigue that doesn’t improve with rest.
- Autoimmune disorders: Conditions like lupus or rheumatoid arthritis can also present similarly and should not be overlooked.
-
Hydration and Nutrition: Continue ensuring adequate hydration and a balanced diet to support recovery.
-
Follow-up on Symptoms: If tonsillar enlargement and white patches persist or worsen, further evaluation by an ENT specialist may be warranted.
-
Rest and Self-Care: Encourage the patient to engage in gentle, restorative activities and prioritize sleep to aid in recovery.
Important Note:
Do not initiate antibiotics without evidence of a bacterial infection, as this could lead to unnecessary side effects and antibiotic resistance. Engaging in a thorough follow-up with her primary care physician is essential for continued evaluation and support.

Persistent Pain in Right Shoulder and Arm After Lifting
Hello, everyone! I’m a 23-year-old male and have been engaged in weightlifting for several years now. Recently, I’ve been struggling with ongoing discomfort in my right shoulder and arm, which I haven’t been able to accurately identify. The pain manifests during particular movements, especially with lateral raises or when my arm is raised to shoulder level while rotating my wrist. Certain pressing and pulling activities can also provoke this discomfort. Rather than feeling sharp, it’s a deep, nagging sensation that sometimes seems localized in the front area of the shoulder or at the biceps tendon, and at other times it feels more like it’s situated between the shoulder and upper arm. Fortunately, there’s no numbness or tingling involved. This issue began while I was working out. I decided to take a break for around two months, but when I returned, the pain persisted. After consulting a physician, I was diagnosed with bicipital tendinitis. Since then, I’ve reduced my upper-body workouts, completely steering clear of shoulder exercises and heavy lifting, and have begun a gentle rehabilitation regimen focusing on external rotations, pendulum movements, and scapular exercises. Despite adhering to this routine for about a week, I haven’t experienced any noticeable improvement. Is it typical for this type of tendon injury to require an extended period for recovery? At what point should I consider diagnostic imaging, such as an ultrasound or MRI? Additionally, are there frequent rehabilitation errors that might impede the healing process? I appreciate your insights in advance!
Understanding EEG Results for My 22-Month-Old Son: Insights Needed
Could someone help clarify this for me? My son, who is just 22 months old, hasn’t started walking yet, becomes tired easily, and has been experiencing behavioral outbursts. He had a febrile seizure in February 2025, followed by another unexplained seizure in April 2025, which led us to consult a neurologist. Since he was 3 months old, he has been receiving therapy from a physical therapist for torticollis. At birth, he spent five days in the NICU due to issues with meconium aspiration. A recent MRI showed normal results, and he also had a follow-up EEG after one conducted in July 2025. The results from this recent EEG were abnormal for a pediatric patient in awake, drowsy, and sleeping states. Notably, there were brief episodes of left frontotemporal delta slowing, which occurred mainly when he was awake and drowsy. There were no signs of epileptiform activity detected. In contrast, the EEG performed back on July 3, 2025, was deemed normal for both awake and drowsy states, again with no evidence of epileptiform irregularities, although it did not capture any sleep data. This examination was prompted by the child's existing history of febrile seizures. Importantly, he is not currently on any anti-seizure medications. The EEG procedure used standard electrode placements per the 10-20 system, conducted a single-lead EKG, and included continuous video monitoring. During the analysis, the background activity was symmetric, indicating some anterior-posterior (AP) organization, with a dominant rhythm of 50-80 microvolts at 7 Hz. His drowsy state was marked by a reduced amount of eye blink activity, less breathing motion interference, and a generalized slowing in theta/delta frequencies. Stage II sleep exhibited spindles and vertex waves patterns. Additionally, there were intermittent bursts of 250-300 microvolts in the left frontotemporal region with semi-rhythmic activity of 2-4 Hz, mostly observed during wakefulness and drowsiness. No definitive epileptiform discharge was noted. Photic stimulation during the test did not elicit a strong response, and hyperventilation was not conducted during this session.
INTENSE Spine Discomfort, Breathing Difficulties, Muscle Twitches, and Sweating
To elaborate on the situation mentioned in the title, I’ve been experiencing unusual muscle twitches and spasms for the past few days, along with some discomfort in my back. However, today, I felt an unexpected sharp pain shoot through my spine, which has left my legs feeling numb and made it impossible for me to sit up straight. Additionally, I’ve been dealing with cold sweats for the last hour and struggling to breathe properly. Perhaps I’m just overanalyzing things and it’s a common occurrence, but the intensity of the pain is overwhelming—it's truly unbearable. I’m shaking quite a bit, and unfortunately, my parents aren’t responding to my attempts to reach them for help. I have a history of a chronic heart condition and arthritis, yet I’ve never experienced pain this severe, especially in my spine. For context, I am nearly 15 years old and female. My current medications include pain relievers, anxiety medication, beta blockers, and some vitamins, though those specifics may not be particularly relevant. I don’t smoke; however, I have tried vaping a few times, which might not matter much, but I thought it was worth mentioning as it was requested.
28-Year-Old Male Experiencing Scalp Sensations Post-Amitriptyline Treatment
I am a 28-year-old man in generally good health, without any cardiac concerns. Approximately a month ago, I encountered intense pain localized to one side of my head, which was unresponsive to paracetamol. However, a single dose of a migraine treatment provided substantial relief. Following that, I began a regimen of amitriptyline, starting at a nightly dose of 10 to 25 mg. While my head pain has diminished significantly—by about 90 to 95%—I now experience occasional uncomfortable sensations on my scalp. These feelings include pins and needles, a cooling sensation, and some crawling feelings near my hairline and ears. There are fleeting moments where I feel brief throbs lasting a second, but I do not have any persistent headaches. To clarify, I do not experience any of the following: - Nausea - Weakness in my limbs - Numbness - Changes in my vision - Coordination difficulties - Seizures The symptoms I have are transient, shifting around and often intensifying when I become conscious of them or as the day progresses. I would like to know: Is it common to experience these sensations during the recovery stage following episodes of neuralgia or migraine-like discomfort? Additionally, could the amitriptyline potentially be causing these temporary paresthetic sensations? I am seeking some reassurance or advice on what is typically observed during this healing process. Thank you.
Concerns About My Toes
Age: 30, Female Currently, I am on the lookout for a reputable podiatrist in my vicinity. However, I've encountered a perplexing issue with my foot. Just last night, I noticed a growth on the side of my toe, something entirely new to me. I maintain a nutritious diet and have a demanding job that requires me to be on my feet quite often. My footwear includes brands such as Brooks Ghost Runners, Hoka Bondi 9’s, and Nike Motiva’s, and I don’t opt for restrictive socks. I also apply Vick’s Vaporub to my feet, a practice handed down from my family, and stick with simple, non-fragrant lotions like Vanicream and CeraVe SA Cream for my skin. In addition, I am curious about the my big toenail's change in color. What might be the underlying reasons for this? Also, I have these persistent dark spots on my toes that I've struggled with since my days on the runway. Despite my efforts, nothing has succeeded in lightening or diminishing their appearance. I'm just looking to determine if there might have been a factor from the past that could have contributed to these issues. I’m not sure what else to include, but I’m open to answering any questions you might have. Thank you for your attention! Best wishes from a worried soul!
