Experiencing Sudden Light Flashes: Is Medical Attention Necessary?
Location: USA, Gender: Female, Age: 57, Height: 5'6", Weight: 145 lbs, Ethnicity: Caucasian Old diagnosis of epilepsy (details to consider!), non-smoker, occasional alcohol consumption. Recently, I have encountered strange flashes of light that seem reminiscent of car headlights or the beam from a strong flashlight. These bright, white bursts appear in my peripheral vision, only to vanish as abruptly as they come. In the past week, this episode has recurred approximately four to five times. Unlike a consistent strobe effect, this is merely a fleeting bright light that disappears when I attempt to focus on it. I believe this phenomenon has predominantly occurred at night, but now I'm having doubts and think I might have noticed one occurrence during daylight as well. There is no recent history of head injury, and I maintain excellent eye health—my vision only requires reading glasses. Overall, I'm in good health and quite active. Although I have a diagnosis of epilepsy, I suspect you might be skeptical, but I genuinely doubt its accuracy. Between 2005 and 2009, I faced sporadic episodes characterized by an aura of déjà vu followed by a peculiar rising sensation in my stomach that often led to tingling in my right arm. After my neurological evaluation, I was diagnosed with medial temporal epilepsy. The condition was labeled as idiopathic adult onset, and even the neurologist remarked that the EEG showed only subtle signs of epileptic activity, leading him to settle on this diagnosis since nothing else seemed to explain my experiences. I was prescribed lamotrigine daily and haven’t encountered any episodes since 2009. In 2015, a standard EEG returned completely normal. At that time, I asked my physician about discontinuing the lamotrigine, but the response was that while it could be feasible, my driver’s license would need to be suspended for six months due to legal reasons, which would hinder my ability to work. Thus, I didn’t pursue stopping the medication. However, over the last couple of years, I have been increasingly irregular with taking my pills, and for the last year, I’ve filled my prescription but not taken the medication at all. The light flashes I’m experiencing now bear no resemblance to what I felt during my previous episodes from 2005 to 2009; the sensations are completely different.

Experiencing sudden flashes of light can be unsettling, especially given your medical history with epilepsy. It's essential to address your symptoms with care because they could suggest a variety of conditions, some requiring prompt attention.
Understanding Your Symptoms: Light flashes in peripheral vision can be caused by several factors such as:
- Ocular migraines: These may occur even without a headache and can cause visual disturbances.
- Vitreous detachment: This is common in older adults and occurs when the gel-like substance in the eye begins to shrink and pull away from the retina.
- Retinal issues: Conditions like retinal tears or detachment can present with flashes of light and should be evaluated urgently.
- Neurological factors: Given your history with epilepsy, it's worth considering changes in your neurological status, especially if the flashes are new or recurrent.
Next Steps:
-
Monitor Your Symptoms: Keep track of when the light flashes occur, their duration, and any accompanying symptoms (like headaches or changes in vision). Note if they happen more often during certain times, like at night or after physical activity.
-
Prioritize Eye Health: Given the potential risks associated with retinal issues:
- Schedule an appointment with an eye specialist (optometrist or ophthalmologist) within the next few days for a comprehensive eye exam. This is especially important if you've noticed any changes in your vision or if the flashes increase in number or intensity.
-
Medication Review: Reflect on your current medication regimen. Since you have been irregular with your lamotrigine, it may be beneficial to reassess your medication and dosage with a healthcare provider, especially considering your epilepsy history. Stability in seizure control is crucial, particularly with new symptoms arising.
-
Hydrate and Rest: Ensure you're staying hydrated and getting adequate rest, as both dehydration and fatigue can exacerbate neurological symptoms.
-
Track Your Medication Intake: To help manage your epilepsy, try to adhere more consistently to your medication regimen as advised by your healthcare provider. If you're having difficulty, consider discussing concerns about the medication with a physician who can provide support or alternatives.
If you experience additional symptoms like headaches, changes in vision, or if the flashes worsen, seek medical attention promptly. Keeping an open conversation with your healthcare providers about both your visual and neurological health is essential. Let me know if you have further questions or need more information!

Interpretation Request for Recent Spinal NM Bone Scan
Hello, doctors. I'm reaching out for your insights regarding a recent NM bone scan of my spine. I've previously undergone a similar scan in 2022, and I'd like to compare the two. To provide context, I am a 29-year-old female weighing 100 kg, and I've been diagnosed with conditions including endplate sclerosis, spinal stenosis, cervical bone spurs, degenerative disc disease (DDD), and mild scoliosis. My medication regimen consists of several prescriptions. Unfortunately, my next appointment with my general practitioner is still a few weeks away, so I would appreciate your assessments on how the latest scan compares to the previous one. Thank you in advance for your help!
Unexpected Eye Issues: Headache and Double Vision Concerns
A 33-year-old female, measuring 1.67 meters in height and weighing 55 kilograms, residing in the Netherlands, experienced a sudden onset of symptoms. Last evening, shortly after dinner, my partner complained of a slight headache localized at the rear of her head. Along with this discomfort, she encountered double vision and noticed her right eye deviating outward. Interestingly, when she shut either eye, the double vision resolved, enabling her to see without distortion. We rushed her to the emergency room later that night. The medical team conducted a variety of assessments, including physical examinations, neurological evaluations, visual tests, and laboratory analyses. Fortunately, all results were normal. However, the doctors found it peculiar that her right eye exhibited normal movement and accurately tracked a pen in all directions when her left eye was closed. The medical opinion suggested that it may be a migraine-related episode, a condition she has experienced previously. Nonetheless, she insists that this feels unlike any migraine she has had in the past. A teleconsultation with a neurologist is scheduled for Monday to arrange an MRI should the symptoms continue. The doctors advised that if her symptoms worsen, we should return to the hospital immediately. Fortunately, after a night's rest, her vision had returned to normal by morning, the headache had subsided, and her right eye was aligned properly. I am understandably concerned, particularly due to her assertion that this does not resemble a typical migraine. Is it possible that this is indeed a migraine, or could it be indicative of another underlying issue? Thank you for your attention to this matter.

Intense Pain in Left Thumb
Greetings, I’ve been experiencing a piercing pain at the tip of my left thumb intermittently. This discomfort is situated within the thumb rather than on the outer skin. It primarily affects the underside of the thumb and surrounds the base of the nail. The pain seems to extend only to the first skin fold, specifically around the distal phalanx. When applying pressure, I’ve noticed some red streaks appearing beneath the surface, alongside the white area. I trust this explanation is clear. This issue has persisted for over a year, occurring sporadically but intensifying as time has passed. Could this be a cause for concern? A bit about myself: I am a 25-year-old female with no significant medical issues in my background. I previously smoked cigarettes for three years, transitioned to vaping, and have been vaping for six years now. I maintain an active lifestyle, frequently going to the gym and participating in various sports such as indoor football and pickleball. I don’t have any known allergies.
