Experiencing Blurry Vision in My Right Eye During Physical Activity
At 30 years old, standing 162 cm (5'3") tall and weighing 53 kg (116 lbs), I’m currently using Slynd, a birth control method containing drospirenone. I abstain from any recreational substances. I've had a history of aura migraines, but they follow a specific pattern that does not align with my current issues. My health profile includes elevated total cholesterol levels (314) and high LDL (243), yet I am not undergoing treatment for these. My triglycerides are low, HDL is in good range, and both my blood sugar and insulin levels remain normal, supported by a HOMA-IR score of 1.1 and a HbA1c within standard limits. Recently, I sought medical advice regarding my troubling eye condition, where my doctor took my concerns seriously. Consequently, I underwent a series of thorough examinations, including a brain MRI with contrast, a comprehensive cardiology evaluation (which featured a 24-hour ambulatory blood pressure monitoring, 24-hour Holter monitor, echocardiogram, and a treadmill stress test), and blood tests aimed at identifying any electrolyte discrepancies. I also consulted with an ophthalmologist. To my dismay, all results yielded no identifiable issues, leaving the medical professionals puzzled. As for my running experience, I have been at it for five years, but this peculiar vision disturbance began only a couple of years back. While I run, I notice that my right eye becomes extremely blurry; the sensation is intense enough that it feels akin to vision loss, often causing me to trip over obstacles due to impaired sight. Remarkably, I experience no headache or any form of discomfort. However, upon stopping my run, my vision immediately returns to normal. This occurs not just when running, but also with other vigorous activities such as dancing, brisk walking, or lifting weights. Given that all my medical assessments are normal, I’m inclined to believe this phenomenon is harmless. Should I consider requesting additional tests from my physicians, or is it possible that they have overlooked something significant?

You are experiencing blurry vision in your right eye during physical activity, which promptly resolves upon stopping. Given that extensive medical tests returned normal results, it is understandable to feel perplexed and concerned about these symptoms. Here’s how you might approach this situation:
Main Points
- Possible Causes: Blurry vision during exertion can be linked to a variety of factors, including changes in blood flow, a temporary disturbance in ocular pressure, or even physiological responses that heighten during physical activity.
- Current Findings: Since thorough testing has not indicated any serious underlying condition, your symptoms may not be due to a structural problem in your eye or serious health issue.
Explanation
The blurry vision could stem from temporary physiological changes when you exert yourself. Activities that increase your heart rate, like running or lifting weights, can sometimes cause fluctuations in blood pressure and blood flow to the eyes, which might explain why you're experiencing this blurriness during workouts but not at rest. Other potential benign causes could include minor dehydration or even visual strain.
Next Steps
-
Self-Monitoring: Keep a detailed log of when the blurriness occurs, including the type of activity, duration, and any environmental factors (like heat or fatigue). This could help identify patterns or triggers.
-
Hydration and Nutrition: Ensure you are adequately hydrated before, during, and after exercise. Sometimes even mild dehydration can affect vision.
-
Gradual Warm-Up: Incorporate a thorough warm-up before activities to help your body and eyes adjust to the increased demands.
-
Visual Exercises: Consider including eye relaxation exercises during breaks in your exercise routine. Focus on distant objects for a minute or two, which may help ease visual strain.
-
Follow-Up: If the blurry vision persists or worsens, or if you notice new symptoms (like vision changes at rest), follow up with your healthcare provider. They might consider referral to a specialist, such as a neuro-ophthalmologist, for a deeper dive into any potential neurological causes linked with physical exertion.
Reassurance
It's good that thorough examinations yielded no concerning findings, which suggests that your symptoms may not be serious. However, keeping track of your symptoms and adjusting your activities based on what you've learned can empower you to manage this situation better. If you feel uneasy or sense that your concerns are not fully addressed, don't hesitate to continue advocating for further evaluation.

Seeking Insights on Ongoing IBS Symptoms
Hello everyone, I'm a 25-year-old male reaching out for some guidance. I've been living with irritable bowel syndrome (IBS) for roughly a year, likely stemming from food poisoning that I experienced. I've managed to alleviate most of the typical symptoms by adhering to a gluten-free, lactose-free, and low FODMAP regimen. However, there's one persistent issue that's lingered, and I believe I've given it ample time to resolve, though it may have been too long based on what my healthcare professionals have indicated about it not being a permanent condition. The specific problem I face is related to my bowel movements, particularly in the mornings. After each average bowel movement, I find myself needing about three to three and a half hours before feeling fully clean. This is often coupled with mucus, a common annoyance for many people dealing with IBS. Is this experience common among others? Will I have to endure this indefinitely? What might this symptom indicate—is it possibly more serious than just IBS?
Seeking Clarity on Thyroid Symptoms and Iron Levels
I’m in my thirties and a woman, and I'm currently feeling a bit perplexed. My thyroid specialist indicated that my symptoms could be linked to iron deficiency rather than Hashimoto's disease. I hold my doctor in high regard and although I meant to ask for more clarification, I didn’t get the chance. Here are some of my iron test results: my hemoglobin is at 11 g/dl, the MCH (Mean Corpuscular Hemoglobin) is measured at 24.9 pg, and my MCG (Mean Corpuscular Volume) stands at 31.2 g/dl. I was under the impression that a more extensive analysis of iron levels would be necessary beyond these figures. If anyone has insights on how these results could indicate iron deficiency over thyroid issues, I would greatly appreciate your thoughts.
Could Kidney Size Be the Hidden Cause Behind My Abdominal Discomfort?
Greetings! I’m a 37-year-old female, weighing 115 lbs and standing at 5 feet 4 inches tall. I have no significant medical history or ongoing concerns, and I do not engage in smoking or drinking. Currently, I am experiencing troubling symptoms: - Swelling and discomfort in my legs, ankles, and feet. At times, the pain is intense enough that walking becomes quite challenging. Additionally, I’ve noticed unusual abdominal pain, but I’m beginning to suspect that it might not be related directly to my stomach. When the pain in my legs is most severe, I often feel pain in the pelvic area, similar to menstrual cramps—though I am not menstruating. Could this be referred pain, or possibly an issue related to my renal system? Moreover, I have been dealing with a persistent low-grade fever that doesn’t seem to resolve. These symptoms have been ongoing for about four months now. I was generally in good health prior to this period and had never needed to take pain relief medication, yet now I find myself coping with daily discomfort. A few months back, I underwent abdominal ultrasound imaging due to these unexplained pains, but it yielded no significant findings. However, a closer examination of the report revealed some variations in kidney volume: - Right Kidney Volume: 176.35, Width: 6.04 - Left Kidney Volume: 120.29, Width: 4.11 Although the imaging focused on my abdomen because of the pain, it seems my left kidney is smaller than usual. This has raised concerns for me, particularly since I have been experiencing more pain on the left side of my abdomen. Does this disparity indicate that my right kidney might be enlarging or that the left one is decreasing in size? From what I’ve gathered, typically, the left kidney is slightly larger, so should these measurements prompt further examination? Additionally, laboratory tests indicated some minor abnormalities flagged as low, which I have not encountered before. Potassium, GFR, and BUN/creatinine levels were lower but have since reverted to my usual baseline. On top of that, I am now observing a slight trend showing lower Carbon Dioxide and a higher chloride level (for instance: chloride at 109 and CO2 at 18). Even though these changes are mild, they still deviate from my normal values. Given all these factors, could what I’ve assumed to be abdominal pain actually stem from my kidneys? I had a colonoscopy combined with an endoscopy last December, and the results were normal. Moreover, I consulted a urologist about the persistent presence of “trace” blood and “trace” leukocytes in my urine, yet no infection was identified. My urine often appears cloudy and contains many specks of white. I’m beginning to wonder if these symptoms might be connected to kidney issues. I mentioned my leg discomfort and the swelling of my ankles—how my socks leave indentations on my skin—but he dismissed it, attributing the swelling to the tightness of my socks, despite it being a long-standing issue. Now, my shoes also feel too tight. I’m uncertain about the next steps regarding these concerns. Any insights would be greatly appreciated! I wanted to seek advice here before deciding whether to pursue further investigation or if I might just be overreacting to these findings. Thank you! 🙏
Seeking Clarity on Hiatal Hernia vs. Rare Conditions
I am a 33-year-old male weighing 215 pounds, and I have been struggling with swallowing issues since August 2025, which have led to episodes of choking and vomiting. Due to my lack of teeth, I am currently in the process of obtaining dental implants. Earlier this year, in February, I visited the emergency room due to worsening symptoms. The lead radiologist examined my case and subsequently ordered a series of CT scans, some of which involved the use of contrast material. When he returned with the results, he mentioned that I am dealing with a hiatal hernia, Kommerell diverticulum, and a right circumflex aorta. I understand that hiatal hernias can sometimes be confused with the other two conditions. Because of this potential for misinterpretation, I am contemplating whether I should seek a second opinion. The proposed surgeries for the diverticulum and aorta could delay my plans for dental implants by at least five months. I am particularly concerned about the likelihood of an incorrect diagnosis from the CT scans. Before needing my teeth removed, I hadn’t encountered any issues with swallowing. This makes me question whether the findings of the CT scan accurately represent my condition, especially considering how uncommon Kommerell diverticulum and a right circumflex aorta are. The attending physician even mentioned that he had never come across these conditions during his extensive experience. Any insights or advice would be greatly appreciated. Thank you!
Could There Be an Issue with My Immune System?
I'm starting to suspect that my immune system may not be functioning properly. At 18 years old and having never experienced any prior immune issues, I find it concerning that since December, I've been unable to go two weeks without falling ill. It seems like I catch every bug that circulates, often within a day of it becoming prevalent. When I do become sick, my body feels incredibly fatigued, making it difficult to even get out of bed. Without medication, I notice no signs of improvement, and my symptoms only escalate, which feels as if my body is unable to heal itself. The only relief I find is through potent antibiotics, yet inevitably, just a week after completing the course, I find myself unwell again. I consulted with my physician, who suggested that a deficiency in vitamins might be the culprit. However, subsequent tests revealed that my vitamin levels are normal. She reassured me that this time of year often brings a wave of illness, and I shouldn't be overly concerned. Despite understanding that seasonal sickness is common, I can't shake off the feeling that there's something more concerning going on. I am left wondering if anyone might have insights into what could be affecting my health. What could possibly be the underlying issue?
