Concerns Over Neck Lump, Weight Gain, and Blood Test Results in a Toddler
I've been uneasy about a lump on my son's neck since he was just 7 months old. Initially, I would only see it briefly when his head tilted back during moments of distress, which made it difficult to assess due to the presence of baby fat. Now that he’s a toddler, the lump is visible whenever he looks up, such as when gazing at the ceiling. It's very soft to the touch, almost indistinguishable, and has remained proportional to his growth, currently resembling the size of a small grape. At birth, he was in the 50th percentile for weight, but by the time he reached his first birthday, he had dropped to the 25th percentile. Now, at 27 months old, he is at the 5th percentile. Despite this, he remains an energetic and cheerful child, meeting all developmental benchmarks, with his height and head circumference tracking consistently. His diet includes a broad range of foods. Given these developments, our pediatrician recommended a complete blood count (CBC) and is now referring him to a pediatric surgeon for further imaging and evaluation. The CBC results indicated some areas of concern. The pediatrician pointed out that the findings could suggest a recent infection, yet my son has been healthy with no sickness for the past five months and continues to be his usual lively and happy self. The most concerning results include elevated lymphocytes and decreased neutrophils. Naturally, I am feeling anxious about the possibility of cancer, particularly since my brother was diagnosed with T-cell lymphoma at 26. While I know that further time and testing are necessary for a definitive diagnosis, I would appreciate any insights regarding the CBC results. Do they appear worrisome given that he is asymptomatic, or are they merely slightly off normal? I'm uncertain about which results might raise red flags for cancer. I understand that cancerous lumps are typically firm and immovable, so could a soft lump like the one I described also indicate cancer? What other explanations could exist for this lump if it has been present for so long? Here are the CBC values for reference: - WBC: 7.53 (normal) - RBC: 5.12 (high) - Hemoglobin (HGB): 13.3 (high) - Hematocrit (HCT): 39.5 (high) - MCV: 77.1 (normal) - MCH: 26 (normal) - MCHC: 33.7 (normal) - Platelet Count: 348 (normal) - RDW: 13 (normal) - MPV: 8.9 (low) - Neutrophils: 25.6 (low) - Lymphocytes: 65.3 (high) - Monocytes: 6.9 (normal) - Eosinophils: 1.3 (normal) - Basophils: 0.8 (normal) - Immature Granulocyte: 0.1 (normal) - Absolute Neutrophils: 1.92 (low) - Absolute Lymphocytes: 4.92 (high) - Absolute Monocytes: 0.52 (normal) - Absolute Eosinophils: 0.1 (normal) - Absolute Basophils: 0.06 (normal) - Absolute Immature Granulocyte: 0.01 (normal)

It's understandable to feel anxious about your son's health, especially with the lump on his neck and the recent CBC results. Based on the information you've provided, the lump being soft and having been present for a long time does not immediately suggest cancer, especially since he is otherwise healthy and meeting developmental milestones. Let's break this down further.
Key Points
- Lump on the Neck: A soft, movable lump in a toddler can often be benign, especially if it has been present for an extended time without significant change. Common causes include lymphadenopathy (swollen lymph nodes), which can occur after infections, and other non-cancerous conditions.
- CBC Results:
- The complete blood count shows elevated lymphocytes and decreased neutrophils, which could indicate a recent infection or a reactive process rather than cancer, particularly as your son remains asymptomatic.
- While the results should be evaluated in context with his clinical picture, by themselves, they do not immediately signal cancer.
Explanation of CBC Findings
- Lymphocytes: Elevated lymphocyte counts can often be seen in viral infections or other conditions that cause the immune system to respond.
- Neutrophils: A decrease can be a transient finding and often reflects a prior infection. It's important to monitor these changes with repeat tests.
- A normal white blood cell count further supports that there's no severe systemic issue currently.
Next Steps
- Continue Monitoring: Keep an eye on the lump for any changes in size, firmness, or signs of tenderness, and take note of any new symptoms (e.g., fever, night sweats).
- Follow Up: Attend the appointment with the pediatric surgeon for imaging and further evaluation as recommended. This can help clarify the nature of the lump.
- Diet and Growth: Maintain a balanced diet and ensure your son is getting enough nutrients. Since he was at the 5th percentile for weight, consider discussing nutritional support or guidance with your pediatrician if concerns persist.
- Stay Informed but Calm: It’s natural to have concerns given your family history, but stay focused on the facts. Most lumps in children, especially those that are soft and moveable, are not cancerous.
Lastly, don’t hesitate to bring up your fears and questions with your pediatrician and the surgeon; they can provide reassurance and clarity regarding the next steps in your son's care. The most important aspect right now is to keep him happy and healthy while you navigate these evaluations.

Assessing My Health Concerns: How Anxious Should I Be?
I’m a 32-year-old woman, weighing 124 pounds and standing at 5 feet 6 inches tall. For over a year, I have been experiencing bright red rectal bleeding. Initially, I attributed this issue to hemorrhoids that developed during my pregnancy two years ago. The bleeding occurs with most of my bowel movements, sometimes happens without one, and on a few occasions, has been enough to stain the toilet bowl significantly. The color of the blood is typically darker than what I observe during a hemorrhoid flare-up. There is a notable family history of bowel cancer on both sides; one family member was diagnosed at age 45, and another at 60. In the past six months, I have encountered several episodes of severe abdominal pain—3 to 4 instances—intense enough to consider a trip to the emergency room. However, the pain usually subsides within about an hour. It’s unusual for me to experience such acute pain, given my high tolerance for discomfort; for example, I once played rugby shortly after dislocating and fracturing my finger. Recently, I mustered the courage to consult with my doctor, who recommended a FIT test, which returned a positive result (30.1). Additionally, I underwent a complete blood test, and aside from having low ferritin levels (7 µg/L), all other results were normal. I have since been referred for a colonoscopy on a two-week waiting list to rule out any possible bowel cancer. Given these circumstances, how concerned should I be? Thank you for your input.
Understanding Possible Seizure Triggers and Recurrence Risks
Health Background: I am a 21-year-old female, standing at 169 cm and weighing 65 kg. Over the past three years, I have been using oral contraceptives. As of this morning, I started taking 25 mcg of levothyroxine along with a weekly vitamin D supplement of 0.266 mg. Recently, I was diagnosed with hypothyroidism and found to have a vitamin D deficiency that I suspect has existed for the last three years. I do not consume alcohol or smoke, and I can confirm I am not pregnant. Two years ago, I experienced a mild concussion. I currently reside in Spain. A couple of months back, in mid-December, I blacked out twice. The second occurrence took place while I was at the doctor’s office after seeking urgent medical care for the initial incident. Following the second episode, I underwent a CT scan and an EKG, both of which returned normal results. Further tests, as directed by my physician, revealed a critical vitamin D deficiency and hypothyroidism; however, he expressed doubt that either of these conditions led to my loss of consciousness. I was then referred to a neurologist, and I am presently awaiting an appointment. Although the waiting period is lengthy, my doctor indicated that I should receive priority for scheduling, although the exact timeframe remains uncertain. The referral document summarized my events, labeling the second episode (which the physician witnessed) as a potential seizure devoid of tonic-clonic movements—a revelation that took me by surprise. After regaining consciousness, I felt extremely disoriented and terrified, struggling to process what was happening. I have no prior history of seizures, epilepsy, or any related conditions, and there is no known family history of these issues. If this indeed was a seizure, what might have triggered it? Additionally, what is the likelihood of experiencing another one? Since that time, I have not had any further incidents, but I have experienced moments where I felt a sense of impending doom, which I managed to overcome. I intend to wait for the neurologist's evaluation, but the uncertainty surrounding a possible neurological condition is quite distressing. Thank you for any insight you can provide!
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.
Understanding Atrial Fibrillation and Thyroid Issues: Variability in Cardioversion Decisions
Hello everyone, I’m reaching out for guidance regarding my mother’s current health situation, and I’d greatly appreciate any shared experiences or thoughts. **My mother's background:** - **Age**: 55 years - **Weight**: Recently dropped to 116 kg from 118 kg in just two days, likely due to diuretics. - **Health history**: Previously an underactive thyroid, undiagnosed and untreated, now presenting as overactive. - **Medications**: Currently taking thyroid medication and a beta-blocker (Rapiblock). **Current health status:** My mother has been hospitalized since Tuesday, experiencing **atrial fibrillation with heart rates exceeding 200** beats per minute due to her thyroid's hyperactivity. - The plan for cardioversion was initially settled on Tuesday. However, the following day, the medical team advised postponing it until her thyroid levels could be stabilized, believing that her heart rate would return to normal once her thyroid condition was managed. - Her **obesity** precludes her from undergoing a transthoracic echocardiogram, and due to her thyroid concerns, she cannot handle contrast dye (this has been a consistent issue for over four years). Therefore, the only feasible option was a **transesophageal echocardiogram (TEE)**, which has yet to be performed. - She has been prescribed various medications including beta-blockers and thyroid treatments in the past. - On Friday, a doctor proposed proceeding with cardioversion; however, the attending senior physician objected. - Today (Saturday), another clinician has expressed a desire to move forward with cardioversion, having initiated a new medication, as the senior physician is unavailable. - **Communication has been unclear**, as we were notified of developments by a nurse rather than the physician in charge, causing confusion and anxiety. - Currently, only a **chest X-ray** is scheduled, and the TEE remains unaddressed. **My inquiries are as follows:** 1. Is it common for medical professionals to have varying opinions and frequently revise medication or treatment plans like cardioversion? 2. Is it safe to conduct cardioversion in the absence of a TEE? I presumed that this was a standard procedure to exclude the presence of blood clots. 3. Is it usual practice to have only a chest X-ray prior to moving ahead with cardioversion? 4. How typical is it for patients or their families to not be directly informed about treatment changes and learn about them through nursing staff instead? I recognize that this cannot substitute for professional medical advice. I’m simply trying to discern whether these circumstances are typical or if we should express our concerns more assertively with the healthcare facility. Thank you for your insights!
