A Brief Lapse in Vision While Brushing My Teeth
A 15-year-old male, standing at 175 cm tall, experienced a fleeting moment where his vision turned completely black mid-tooth brushing. This incident left him anxious, wondering if it could be a sign of a blocked blood vessel. Alternatively, he contemplated if it could simply have been an issue with the lighting. In the aftermath, he pondered whether it would be wise to go to bed or if further action was needed.

It's understandable to feel anxious after experiencing a sudden lapse in vision, even if it's brief. Such incidents can arise from various causes, many of which are temporary and not serious. It's good that you're being attentive to your health.
Possible Causes:
- Temporary Vision Changes: This could be due to a range of factors, including changes in lighting, fatigue, or even a brief drop in blood pressure.
- Other Considerations: If the episode was very brief and there were no other symptoms (like dizziness, headaches, or lasting vision changes), it’s likely not related to a serious condition. However, ongoing or repeated symptoms should not be ignored.
Next Steps:
-
Monitor Symptoms: Pay attention to any further occurrences. Keep track of what you were doing when it happened, how long it lasted, and any associated symptoms such as dizziness or headaches. This information can be valuable.
-
Stay Calm and Rest: If you’re feeling anxious, try to relax. It’s perfectly fine to go to bed if you feel tired, as rest can help your body recover.
-
Avoid Potential Triggers: Ensure you’re well-hydrated, eat regular meals, and stand up slowly after sitting or lying down to avoid sudden changes in blood pressure.
-
Consider Lighting Conditions: If this only happened once with no further issues, it might have been related to the bathroom light or your angle while brushing your teeth.
-
Follow Up if Needed: If you experience more lapses in vision, or if other concerning symptoms arise (like severe headaches, confusion, or prolonged vision issues), definitely consider seeking a healthcare professional for a more detailed evaluation.
Caring for your overall health and noting any worrying changes is key. If you have more questions or experience further incidents, please feel free to ask.

Experiencing Lip Numbness Following General Anesthesia
At 29 years old, I've recently undergone a surgical procedure on my head, and now I've noticed that only part of my lower lip has become numb. After contacting the hospital ward, the doctor reassured me that this numbness is unlikely related to the surgery itself; it might instead stem from trauma caused by the intubation during the procedure. I’ve checked my lip thoroughly, and there's no visible skin damage or any noticeable changes—it's just a complete lack of sensation. The doctor advised me to visit the emergency department should my symptoms not improve, yet I’m uncertain if my situation truly qualifies as a medical emergency. Is experiencing this kind of numbness common following such procedures?
Persistent Unexplained Lesion on Inner Thigh
At 24 years of age and female, I have been dealing with what appears to be a minor blood blister located on the inner part of my lower thigh for approximately four to five years. This lesion tends to appear and disappear over time. Occasionally, it resembles an empty blister, only to later expand slightly and appear filled with a dark liquid. When it reaches its largest size, it is comparable to a Tic Tac and has a slight elevation. Although it does not cause any pain, I can feel its presence as I walk, particularly when my thighs come into contact with one another. Furthermore, I wish to note that recently there has been the first instance of some redness surrounding the area. I will provide additional details in the comments.
Bilateral Finger Numbness
A 46-year-old male, who smokes, weighs 77 kg and stands at 6 feet tall, consumes beer occasionally and has a diagnosis of ADHD. His current medications include Elvanse at 70mg, pregabalin at 600mg, and venlafaxine at 150mg. In the past year, he underwent a series of extensive tests for fatigue, which included assessments for B12 levels, iron, glucose, and vitamin D. These led to the use of a CPAP machine. For more than a year, he has experienced mild numbness in his fingers. Recently, he took up a cleaning job, and in the last three months, he has noticed that the numbness in his right hand has intensified, affecting his thumb, index, and middle fingers. Meanwhile, his left hand shows significant numbness in the ring and middle fingers, which paradoxically have areas of heightened sensitivity—any slight impact or pressure causes noticeable pain. He struggles increasingly with hand functionality, often dropping items and finding it difficult to perform tasks such as opening jars or fastening buttons. There is also a notable weakness in his non-dominant left hand. Initially, he suspected that these symptoms were related to carpal tunnel syndrome but now questions the likelihood of both hands exhibiting similar issues, especially with the left one deteriorating more rapidly over a short span of three months. With an appointment scheduled with his general practitioner on September 3rd, he is contemplating whether he should seek another opinion sooner. Thank you for any insights you can provide.

Heart Ultrasound Examination Results
Greetings, I am a 29-year-old male experiencing unusually frequent extrasystoles for the past five days. Here are the findings from my recent heart ultrasound: The ultrasound was performed while I was experiencing tachysystole. Findings Summary: The size of the left ventricle and its systolic function are both within normal limits, with an ejection fraction of 59%. No regional contractility issues were detected. However, there is evidence of diastolic dysfunction characterized by impaired relaxation. The filling pressure is normal, and the left atrium is of a standard size. The mitral valve appears normal, as does the aortic valve, and both the sinus of Valsalva, aortic arch, abdominal aorta, and ascending aorta are normal. Likewise, the dimensions and systolic function of the right ventricle fall within normal parameters. There is minor tricuspid valve insufficiency noted (+1/+4). Additionally, the systolic pressure in the pulmonary artery is within the expected range, and both the pericardial and pleural cavities are normal.
