Worries About My Blood Tests Despite Feeling Well
As a 44-year-old male, standing at 5'11" and weighing 120 pounds, I am under observation for chronic kidney disease (CKD). Since birth, I've had only one kidney and am currently managing high blood pressure with a dosage of amlodipine at 5mg. Previously, I was prescribed bisoprolol but discontinued it after being put on this new medication. My daily routine includes taking a multivitamin and magnesium supplements. What perplexes me is my high blood pressure, as I do not conform to the typical profile of individuals affected. My lifestyle is quite healthy; I do not smoke, drink alcohol, or use drugs, and I maintain an active routine, engaging in workouts three to five times a week. Additionally, my job involves considerable physical labor, which keeps me consistently active. Recently, however, I received alarming blood test results indicating a decline in my kidney function, with an estimated glomerular filtration rate (eGFR) at 13 and elevated potassium levels. Since then, I've been anxiously searching online for explanations for these high creatinine and potassium levels. Interestingly, I feel fine aside from mild fatigue from an early start to work today. My appetite remains robust, and I’m not experiencing any symptoms like swelling, coughing, or itching. Although I might be urinating slightly more than usual due to increased water intake for hydration, I do not exhibit indications typically associated with significant kidney impairment. In fact, today I felt quite energetic, which is unusual after a long workday. During my blood draw, I was incredibly anxious and even shook due to nerves; I tend to tense up at the needle's insertion, which adds to my unease. I've read that such stress can lead to a false increase in potassium levels. Additionally, I had completed some squats earlier that morning and consumed a protein-rich breakfast, which might have affected my creatinine results as well. Furthermore, my recent complete blood count reflected an improvement in the anemia I had been facing, and a urine analysis showed that my creatinine excretion was well within the normal range—not just low normal but firmly in the middle. So what is actually happening regarding my kidney health? Am I on the verge of losing my kidney, or is everything manageable? The stress from this situation itself may be compounding the problem. While I usually handle life’s challenges well, this one genuinely unnerves me.

Main Points: Your recent blood test results indicate some concerning changes in kidney function, but your overall health and activity levels suggest you may not be in immediate danger. Stress and recent activities may have affected your blood test results. It’s important to manage your anxiety and focus on your health steps moving forward.
Explanation: It's understandable to feel anxious about high creatinine and potassium levels, especially given your medical history. Chronic kidney disease (CKD) can cause fluctuations in kidney function, and eGFR levels can vary due to various factors, including stress, hydration status, recent physical activity, and dietary choices. While an eGFR of 13 indicates a decline in kidney function, it's essential to consider your overall context.
-
Anxiety and Blood Test Results: The anxiety before your blood draw, as well as any physical exertion (like squats) that you did beforehand, can lead to temporary increases in potassium levels and affect creatinine results. It's common for stress to influence blood test results.
-
Current Symptoms: The fact that you're feeling well, with a good appetite and only mild fatigue, is a positive sign. It's crucial to monitor how you're feeling overall rather than focusing solely on lab numbers, as kidney function can sometimes improve over time with the right management.
-
Ongoing Monitoring: High potassium levels and declining kidney function should be monitored closely, but they're not necessarily signs that your kidney will fail imminently, especially if you're asymptomatic aside from mild fatigue.
Next Steps:
-
Stay Hydrated: Continue to drink plenty of fluids, as staying hydrated is vital for kidney health. However, do not overdo it; balance is key, especially with potassium levels.
-
Monitor Diet: Pay attention to your potassium intake. While foods high in potassium are generally healthy, you may wish to limit excessive portions of foods like bananas, potatoes, and oranges, particularly if your levels are elevated.
-
Focus on Stress Management: Consider techniques for reducing anxiety around blood tests and your health, such as mindfulness, deep breathing exercises, or talking to a counselor if stress becomes overwhelming.
-
Follow-Up Testing: Keep track of your blood pressure and kidney function with regular tests as directed by your healthcare provider. They may recommend more frequent monitoring temporarily to track these changes closely.
-
Communicate with Your Healthcare Provider: Keep an open dialogue with your healthcare provider about how you're feeling, and do not hesitate to discuss any concerns regarding your results. They may want to repeat tests to confirm the results, especially given your physical activity and stress on the day of the blood sample.
Remember, managing CKD and hypertension is a journey. With your healthy lifestyle and consistent management, you're actively taking steps to support your kidney health. If you have more questions or concerns, feel free to ask.

Exploring Inositol and CoQ10 for Managing PCOS Symptoms
As a 28-year-old female, I have faced the challenges of polycystic ovary syndrome (PCOS) since my teenage years. Starting from the age of 16, I have dealt with highly irregular menstrual cycles, occurring anywhere from three to eight months apart. My diagnosis has been substantiated through two ultrasounds and blood tests revealing elevated androgen levels. Despite maintaining a healthy diet and leading an active lifestyle—balancing my work as an environmental biologist with gym sessions alongside my husband—I continue to wrestle with weight management. Other symptoms impacting my daily life include significant hair loss, unwanted facial hair, and persistent fatigue. In my journey to manage PCOS, I previously sought counsel from a gynaecologist, who primarily suggested hormonal birth control as the main approach to alleviate my symptoms. Although I adhered to this recommendation for several years, the hormonal changes negatively impacted my mood, leading me to discontinue its use. Another alternative proposed by my gynaecologist involved androgen blockers, but these are not suitable for me since my husband and I plan to start a family in the next two to three years. Recently, my research led me to discover that supplements like Inositol and CoQ10 might effectively combat insulin resistance and lower androgen levels. They are purported to improve various symptoms associated with PCOS, including the regulation of ovulation, all while boasting minimal adverse effects. I am curious about the viability of these supplements as alternatives to hormonal birth control or androgen blockers in managing my PCOS symptoms.
Seeking Clarity on My Spinal Tap Results: A Bit Anxious
I am a 31-year-old woman experiencing a continuous headache for the past four months, accompanied by feelings of nausea and exhaustion. I take Lexapro each day to manage my mental health. I have a history of migraines and headaches, but this recent episode doesn't align with my previous experiences. Here are the findings from my spinal tap: - **Opening Pressure of Cerebrospinal Fluid (CSF)**: 9 cm H₂O - **Presence of Red Blood Cells (RBCs) in CSF**: 2,570 - **Total Protein Level in CSF**: 107 mg/dL - **ACE Level in CSF**: 4.4 - **Other Tests on CSF**: Results were normal. - **Brain MRI and MR Venography**: Both tests yielded normal results. - **Blood Test Results**: Normal results were obtained. Given these results, I'm feeling a bit uneasy and I’m hoping to better understand what they might indicate about my health.
Concern Regarding Persistent Tongue Bump with White Coating
I am a 24-year-old male, standing at 190 cm tall and weighing 109 kg. For the past five weeks, I've experienced a peculiar issue on my tongue. Specifically, there's a noticeable bump on the right side near the tip, which I believe may have been developing over time, although I'm not entirely sure about that timeline. Recently, I've been troubled by an unusual sensation, including dryness, an odd taste, and a slight decrease in my sense of taste. Additionally, I've observed a white coating that is more pronounced on the aforementioned side of my tongue. The bump in question: - Does not cause any pain. - May have increased slightly in size over the weeks, though I'm uncertain. - Appears smooth with a pink surface, free of bleeding or ulceration. Given that this issue has persisted for over a month, I am feeling quite anxious and am concerned that it may indicate a serious problem. I have no significant medical history, but I confess that my dental hygiene has not been up to par, as I haven’t been brushing regularly. At this moment, I’m also under medication for H. pylori, known as Pylera, but this tongue concern predates my treatment. I am a non-smoker and am reaching out for any insights on this condition. Has anyone experienced something similar? Could this be a sign of irritation, infection, or something benign? I really appreciate any guidance you could provide. Thank you!
Experiencing Clear Fluid from Ear with No Discomfort: Should I Wait for My Appointment?
I am a healthy 57-year-old female, weighing 120 pounds and standing 5 feet 5 inches tall. My daily medications include 100 mg of Losartan for effectively managed high blood pressure, 200 mg of Lyrica taken twice daily for post-herpetic neuralgia, 100 mg of Synthroid following treatment for thyroid cancer, and a combination hormone replacement therapy patch. Additionally, I take Zyrtec and Flonase every day to combat allergies. Since October, I have been dealing with persistent tinnitus in my right ear, accompanied by some pressure and a muffled sensation. Recently, I've noticed that when I speak, it feels akin to the sensation I experience when my ears clear during a flight after chewing gum—my voice sounds amplified in my head. I've scheduled an appointment with a physician's assistant in an ear, nose, and throat (ENT) office for the end of March due to my worries about the tinnitus and any potential hearing impairment. Yesterday, I noticed that my ear emitted a clear fluid. Thankfully, there was no associated pain. The fluid was somewhat thicker than water, completely odorless—unlike the unpleasant discharge I recall from my daughter's ear infections—and there was no sign of blood. Could this indicate a perforated eardrum? I suspect this might be the case, but can this occur without an underlying infection? Should I seek attention sooner than my appointment in March? I would prefer to avoid urgent care during flu season; however, if this situation is serious, I am prepared to take precautions and visit.
Understanding the Increased Pain in My Foot While Reclining
At 30 years old, I am nearing the five-week mark since undergoing surgery on my metatarsals. I've encountered a troubling issue: I can’t seem to find comfort when lying down, whether it’s with my foot raised or lying flat. My pain level escalates to a severe 10 out of 10, unless my foot is making contact with the floor or I dangle my leg off the side of the bed so that my toes touch the ground. Is this situation typical for someone in my circumstances? Are there any suggestions that might assist me in getting a better night's sleep?
