Persistent High White Blood Cell Count: What Could It Mean?
As a 33-year-old male who recently battled COVID-19, I’m currently dealing with some health concerns. It's been three weeks since my diagnosis, and during that time, my doctor initiated a course of antibiotics to treat a secondary infection of bacterial pharyngitis. Today marks the tenth day of my antibiotic therapy. Although I haven’t experienced any fever and my sore throat has almost resolved, I’m concerned about my persistently elevated white blood cell (WBC) count. Could this be a typical response even after such an extensive course of antibiotics? I can’t help but worry about the possibility of a blood disorder. To provide more context, my lab results indicate: - WBC: 9.88 x 10^3/uL - Neutrophils: 61.4% - Lymphocytes: 29.1% - Monocytes: 6.0% - Eosinophils: 2.4% - Basophils: 1.1% - RBC: 5.57 x 10^6/uL - Hemoglobin: 168 g/L - Platelets: 380 x 10^3/uL - PDW: 8.8 fL Given this information, I would appreciate any insights into why the WBC count remains high and whether this is something I should be alarmed about.

It's understandable to feel concerned about your persistently elevated white blood cell (WBC) count following your recent health challenges with COVID-19 and a bacterial pharyngitis infection. Elevated WBC counts can happen for various reasons, especially after infections, but it's important to interpret these numbers in context.
Explanation
A normal white blood cell count typically ranges from about 4.5 to 11.0 x 10^3/uL. Your count of 9.88 x 10^3/uL is within the normal range, though on the higher side. It is common for WBC levels to remain elevated for a period after an infection as the body responds to inflammation, healing, and potential residual infection. The specific breakdown in your lab results shows that your body is effectively employing neutrophils and lymphocytes, which are key components of the immune response.
Next Steps
-
Continue Monitoring: Keep an eye on your health. If you notice any new symptoms such as fever, increased fatigue, or unusual bruising or bleeding, note these changes as they could be important.
-
Hydration and Rest: Ensure you stay well-hydrated and get plenty of rest, as both can help your recovery.
-
Complete Antibiotic Course: Finish the course of antibiotics as prescribed by your doctor, even if you feel better, to ensure that the infection is fully cleared.
-
Follow-Up Testing: If your WBC count remains the same or continues to rise after completing your antibiotics, discuss with your healthcare provider about the need for further testing. This might include repeat blood tests or additional investigations to rule out other causes.
-
Healthy Lifestyle: Maintain a balanced diet rich in fruits and vegetables, exercise regularly, and manage stress through relaxation techniques, all of which can support your immune system and overall health.
Remember, while your concerns are valid, many factors can influence WBC counts, especially after infections. You're taking steps in the right direction by seeking clarity and remaining attentive to your health. If you have more questions or need further clarification, feel free to ask.

Micronodules Detected in Lung
Hello, I recently underwent a coronary artery calcium (CAC) scan to assess arterial plaque, and I was pleased to receive a favorable score of 7.75. However, the report highlighted the presence of several clustered micronodules located in the right upper lung, accompanied by adjacent ground-glass opacities. I am a 60-year-old male, 6 feet tall and weigh 190 pounds. I do not currently take any medications and generally enjoy excellent health. There is a family history of heart disease on my father's side. Additionally, I am a non-smoker, apart from occasional use of cannabis, and consume alcohol very infrequently. Thank you in advance for any insights you can provide!
Concerns About My Daughter's Morning Health Issues
My 17-year-old daughter experiences troubling symptoms each morning, particularly on days when she needs to rise early for school or work. She often wakes up feeling dizzy and nauseated, accompanied by a rapid heartbeat exceeding 100 beats per minute. This situation prevents her from being able to eat and may persist for several hours, or in some cases, throughout the entire day. Standing at 5 feet 8 inches tall (172 cm) and weighing 121 pounds (55 kg), her physical health otherwise seems fine. I have a personal history of inappropriate sinus tachycardia (IST), which is why I take beta-blockers for management. A few years ago, she consulted a cardiologist regarding her frequent episodes of near-fainting, who recommended increasing her water intake and adding more salt to her meals. Given the persistent nature of her symptoms, I am contemplating whether a follow-up appointment with the cardiologist is warranted, especially since all previous tests, including ECG and ultrasound, came back normal. This situation significantly affects her daily life, restricting her ability to engage fully in school and work. Any suggestions would be greatly appreciated!
Bleeding Concerns with IUD and Yeast Infection Treatment
I’m a 20-year-old female, standing at 5’4” and weighing 155 pounds. Hello everyone! Approximately three weeks ago, I had the Kyleena IUD placed, and everything felt fine afterward—I can still feel the strings. I noticed some mild spotting that was brown for about a week, followed by my menstrual period, then continued with light spotting. Recently, I suspect that I might have developed a yeast infection, which I am currently addressing using Monistat 7. I applied the first dose yesterday. To clarify, I am certain that I am not dealing with a sexually transmitted infection. However, I’ve observed an increase in bleeding, significantly more than what I’ve experienced before. The blood appears to be light red, and I would compare the amount to the lightest day of my period. I could comfortably go an entire day without needing to change my pad, though I still do it for hygiene reasons. Is this a common occurrence? Most of the bleeding took place this morning after I woke up, coinciding with the Monistat cream leaving my body. Under what circumstances should I seek medical advice regarding this issue instead of waiting to see how the treatment progresses?
Chronic Joint Pain Since Childhood
Since I was eight years old, I’ve endured intense and persistent pain in my joints. Initially, the discomfort was primarily in my knees, characterized by a sharp sensation right beneath the kneecap. As someone on the autism spectrum, I often visualize a strange, soothing thought: the idea of removing my kneecap and using an ice cream scoop to relieve the pressure underneath it. My parents sought help from several medical professionals, all of whom attributed my symptoms to growing pains. I even underwent cancer screenings at the age of nine because doctors felt my level of discomfort was excessive for mere growing pains. At school, I frequently had to wear dual knee braces. When I turned 14, I had a CT scan, but the results were inconclusive; doctors continued to insist it was just growing pains. At 18, I had an X-ray that also revealed nothing abnormal. Now at 20, my joint pain persists and is progressively worsening. My hands now ache in addition to my knees, and on particularly bad days, the pain radiates down to my ankles, making walking and sleeping almost impossible for half the week. The discomfort has entirely hindered my ability to work. My family and I strongly suspect that I may have some form of arthritis, but I struggle to convince the medical community of this due to my young age. My father, who suffers from arthritis himself, often empathizes when I express my pain, telling me, "that sounds familiar." I have broken down in front of numerous doctors, pleading for assistance, yet I consistently leave without answers, only to be scheduled for more scans that come back normal. The medical care I have received thus far has been far from satisfactory; for instance, I was prescribed eye drops that nearly resulted in serious damage to my vision when I consulted an eye specialist. This is just one of many frustrating experiences I’ve faced. I feel completely overwhelmed and in agony, and I have no way to reach out for specialized medical help since my only means of transportation is my father, who is also afflicted by arthritis. I feel lost and in deep pain without a clear path forward.
Seeking Guidance on Persistent Chest Discomfort After Extensive Testing
I'm a 43-year-old male, standing at 5'11" and weighing 180 pounds. My journey began around March to April of 2025 when, despite regularly hitting the gym four times a week, I was struck by severe chest pain along with frequent belching and a tight feeling in my diaphragm. At times, the pain became so intense that I feared it might be a heart attack. **Medical History:** In May 2019, I received a diagnosis of **PVS** and have since been under the care of a cardiac electrophysiologist. Upon experiencing these new symptoms, I consulted my EP, who conducted an EKG right then and set me up with a 7-day heart monitor. The results showed no irregularities. Subsequently, I was directed to a cardiologist, who carried out both a **stress test** and an **echocardiogram**, both of which yielded normal findings. Afterward, I returned to my primary care physician, who speculated that my gallbladder might be involved. An **ultrasound** was performed but revealed no issues. I then requested a **chest X-ray**, which also came back normal. My PCP then considered the possibility of a **hiatal hernia** and referred me to a gastroenterologist; unfortunately, that appointment took almost **five months** to materialize. In the meantime, my symptoms persisted, prompting me to cease weightlifting and switch my focus to **cardio and running**. Surprisingly, these activities didn’t exacerbate my symptoms, though the chest pain remained constant. When I finally saw the gastroenterologist, they suggested an **upper endoscopy**, which took another roughly three months to arrange. During this procedure, I was diagnosed with **Eosinophilic Esophagitis (EOE)**, a condition I had not previously experienced. The doctors also placed a pH monitoring device for acid reflux assessment, which indicated **no unusual acid exposure**. Following this, I began a treatment plan that included a swallowed steroid inhaler and an increased dosage of **omeprazole**. Sixty days later, I underwent another endoscopy, which showed that the EOE had largely resolved, with minimal residual symptoms. Unfortunately, my chest discomfort persisted without any improvement. It has now been about **a year** since these issues emerged, and I still have not found substantial relief. A recent chest MRI completed at a dedicated imaging center revealed no abnormalities. I entertained the idea of **costochondritis**, but again, the MRI did not support that hypothesis. The only minor relief I find comes from consciously pulling my shoulders back and expanding my chest. I continue to experience discomfort around my **diaphragm** and tenderness in the area of the **xiphoid process**. My PCP prescribed a steroid pack, which was somewhat beneficial for the pain but failed to alleviate the pressure or constant discomfort. At this juncture, I feel quite lost and uncertain about my next steps. I would greatly appreciate any insights or experiences from others who have faced similar issues. Additionally, if there are any physicians here willing to offer advice, I am open to traveling to find the answers or relief I'm desperately seeking.
