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.

Recurring Health Issues Over Several Weeks
**Age:** 19 **Gender:** Female **Height:** 5 feet 3 inches **Weight:** 141.6 lbs **Ethnicity:** Caucasian **Duration of symptoms:** Around a month **Affected area:** Lower abdomen and swollen pituitary gland **Current medications:** Hyoscyamine sulfate and Zofran (prescribed during ER visit) Hello, Reddit community! This is my first time posting here, and while I do have forthcoming medical appointments at the end of this month, I wish to share my experiences in detail. If graphic descriptions make you uncomfortable, consider this too intense to engage with. To give you some context, on July 10th, I woke up feeling generally unwell. There was no nausea, yet I was frequently vomiting alongside having dark green to black, soft, and tar-like stools. Notably, the odor wasn’t unpleasant, merely typical of stool. I had to collect a sample for tests, which meant dealing with it myself, and it was somewhat distressing. Initially, I thought my discomfort was due to nerves because I was scheduled to pick up a friend for a concert at my boyfriend's place. I began my day around 7 or 8 AM, dealing with continuous vomiting and rapid trips to the bathroom. Although I experienced some relief initially, subsequent bathroom visits produced only small amounts of stool until nothing came out; eventually, I was retching only saliva. Despite feeling poorly, I persevered and fetched my friend, as she had spent a great deal on concert tickets. I felt somewhat better on the return trip and that evening. However, the concert’s morning was a different story. I woke up doubled over in pain, drenched in sweat, and experienced more vomiting along with similar stool consistency. We managed to attend the concert, but after eating a pretzel, I had to leave and missed a significant part of the show. It was quite frustrating. The trip home was a repeat of earlier vomiting and bowel distress, leading to me collapsing into bed. On day three, I needed to return my friend home, yet I awoke at 8 AM with intense pain primarily in my lower abdomen, with cramping around my uterus and gastrointestinal area, and I was also sweating and shaking. The ER staff conducted a CT scan, administered IV fluids, and tested my urine, but couldn’t determine the issue and sent me home with medication that surprisingly provided some relief. This included a stomach relaxant and nausea medication—though I was retching without feeling nauseated; it felt like my throat was perpetually open, producing saliva. After leaving my boyfriend’s place, I was unwell for nine more days while staying with my grandma. It lasted from the 10th to the 17th or 18th, but eventually, my symptoms diminished, leading me to believe I had overcome the illness. I did notice, however, an increase in swelling of my pituitary gland from all the vomiting, but it felt manageable. Interestingly, my symptoms usually re-emerged at night or early morning, worsening upon awakening but gradually easing off. Fast forward to August 4th: I had been symptom-free for about a week. I underwent wisdom tooth removal and felt fine throughout the day until around 6 PM when the black, tarry stool returned along with severe abdominal pain and that troubling sensation in my throat. The next morning, I vomited again and could only produce stool intermittently, experiencing frustrating efforts in the bathroom. It felt like no matter how much I attempted to go, I would end up sitting for an extended duration for minimal results. Now, I find myself on day three of sleeplessness this early morning, trying to stave off sickness before bed to ensure a peaceful night devoid of waking up in pain. Since the 5th, I’ve retched multiple times, including twice that day, three times the following day, and just recently purging stomach acid at 3:30 AM alongside a brief episode of tarry stool. Soft, cold, and lukewarm foods are all I can manage currently, completely avoiding anything requiring suction or straws. I’m seeking insights into whether anyone else has experienced similar symptoms and any understanding of what might be happening within my body that I’m currently unaware of. **Symptoms Overview:** - Vomiting without accompanying nausea - Black green tarry, sticky stools produced in short intervals - Cramping and aching in the lower abdomen, described as a burning sensation that shifts when I change positions - Persistent swelling of my pituitary gland, which started on the fourth day of my initial episode and has since subsided somewhat but continues to be present. This marks the second incidence of these recurring symptoms, and I find myself staring in the mirror trying to reassure my reflection out of fear for what’s happening to my health. Any advice or thoughts would be greatly appreciated!
Dislocated Shoulder - Day 7 Update
Age: 39, male, generally fit and active. While on a solo expedition, I had a mishap and slipped down an outdoor iron staircase that had become slippery. This unfortunate incident led to my left shoulder being dislocated for the first time and my left ankle fracturing in three places. Upon reaching the emergency room, medical professionals managed to realign my shoulder after approximately three hours post-injury. They advised me to keep my arm immobilized in a sling for one week. Initially, I adhered to this guideline, keeping my arm in the sling for the first two days. However, I soon found it necessary to remove the sling to maneuver with crutches and to type. Living independently on the second floor of an apartment without an elevator posed additional challenges, so I took extra care not to raise the injured arm above shoulder level or position it behind my back, ensuring it remained as close to my side as possible. Upon consulting another physician after returning home, I learned that it would be better to keep the arm in the sling for a total of three weeks without any exceptions. I also reached out to two other doctors for additional insights, and their advice varied to some extent. Overall, the consensus among the professionals seems to suggest: - Maintain the sling on my shoulder for three weeks. - While removing it occasionally to navigate with crutches and to type is not preferred, it should not result in long-term harm. - A follow-up MRI and physical therapy evaluation is scheduled for two weeks from now, at which point the arm may be released from the sling. Throughout the day, I experience mild tenderness in my arm, scoring about 1 or 2 out of 10 on the pain scale. Despite this discomfort, I feel that I am managing well. I am eager to ensure the best possible recovery. However, the practical aspects of daily life make it challenging to remain completely immobile. What actions can I take safely during this healing period? Is it permissible to apply 75% of my weight on my uninjured arm while using crutches? Have I caused any irreversible harm to my shoulder? I welcome any advice or recommendations on how to proceed!
Is High Ketosis a Concern for Non-Diabetics? Understanding Low Blood Sugar in the Context of Ketones
Hello, I am a 38-year-old female weighing 99 pounds with a BMI of 17. For various personal reasons, I've been steering clear of carbohydrates lately, despite understanding the potential health ramifications. This change in diet has coincided with a resurgence of my previous eating disorder symptoms; I have a history of severe anorexia and have experienced a significant weight loss recently. My ketone levels, as measured by a blood monitor, are at a striking 7.3 mmol/L, while my blood sugar consistently hovers under 54 mg/dL. It’s obvious that I am in a state of ketosis. However, considering that I am not diabetic, I wonder if this poses any real risk to my health. Can my elevated ketone levels offset the dangers associated with low blood sugar, especially since it dropped to 36 mg/dL last week? In addition to this, I also have several health concerns, including rheumatoid arthritis, osteoarthritis, anemia, obsessive-compulsive disorder, a history of severe anorexia, and post-traumatic stress disorder. My current medications include Benepali (etanercept), tramadol, gabapentin, amitriptyline, fluoxetine, an estrogen patch, omeprazole, and propranolol.
Experiencing Fainting Spells After Using Cannabis
Hi everyone, I'm a 20-year-old female, standing at about 5'8" and weighing roughly 160 pounds. A few days ago, while attending a festival, I decided to take two hits from a joint. I was cautious not to overindulge, but shortly after, I started experiencing blurred vision and intense sweating. I instinctively clutched my sister as I felt myself turning pale and ended up fainting for a brief moment. During that time, all I could see was white, though I remained aware of my surroundings through other senses. Given the large crowd, my sisters quickly assisted me in navigating through it, and once I caught a breath of fresh air, my vision returned. I felt lightheaded but recovered within a few minutes.
Understanding Persistent Rib Pain Despite Negative Imaging Results
A woman in her late 40s is facing a perplexing issue with lingering discomfort in her ribs. Here's a summary of her situation: Two months ago, she experienced a tight embrace from a friend, which she believes initiated her pain. That night, she woke up with significant discomfort while shifting in her sleep, prompting her to visit urgent care the following day. During that visit, X-rays were taken, revealing what the urgent care doctor initially thought were about seven broken ribs. She was prescribed a combination of over-the-counter pain medications and scheduled for a Dexa scan the next day, which showed a bone density reading of -2.1. However, a few days later, a formal review by a radiologist contradicted the urgent care findings, indicating no signs of fractures on the X-rays. Consequently, her primary care physician (PCP) concluded that she was fine and advised against further investigation into osteopenia given her bone density results. Still concerned, she insisted on having a CT scan, which was conducted three weeks after the initial injury. Yesterday, she received the results, revealing again that neither the PCP nor the radiologist had found any fractures, lesions, or other abnormalities that could account for her ongoing pain. Her primary concern now is understanding the persistent pain she feels in three specific areas of her left rib cage: the lower front, the upper back near her spine, and the lower left side toward the back. While she began tapering off the acetaminophen and ibuprofen that she had been taking since week three, she still occasionally uses a lidocaine patch on the upper back area. She describes the pain in that spot as sharp, in contrast to the other regions where the sensation is more of a dull pulling. Although it's evident that she is improving, she does not feel completely healed. Given that her imaging tests have shown no clear issues, she is left wondering why the pain persists.
