Severe Nausea and Disorientation Triggered by Bright Light During Eye Exam
What caused this unsettling experience?! During my eye examination, I was not given dilating drops, yet the doctor directed a bright light into each eye individually for a letter reading test. Almost instantly, I felt faint, my skin became clammy, and I started sweating. I experienced a darkening of my peripheral vision, almost as if I were on the verge of collapsing. Simultaneously, I was hit with waves of nausea and an urgent need to use the restroom—an overwhelming sensation reminiscent of a comedic moment from Kick-Ass 2. I managed to inform the eye doctor that I needed a bathroom urgently, stumbling over my words due to the intense confusion I was feeling. Making my way to the toilet, I anticipated vomiting or experiencing severe gastro distress. However, as soon as I reached the restroom, remarkably, the queasiness and discomfort vanished. Despite that relief, I remained notably disoriented for approximately half an hour, with a sensation akin to mild drunkenness. I have a medical background that includes seizures, migraines, and icepick headaches, all of which can be triggered by light or occasionally by visual disturbances, but I have never encountered anything like this before. The intensity of nearly losing consciousness just from a bright light was shocking. It’s baffling, especially since I had eaten adequately that day, ruling out low blood sugar as a factor. For the past five years, I have consistently taken my prescribed medications: 150mg of Lamictal, 50mg of Seroquel, Zovia, and 40mg of Prozac. Despite the episode resolving quickly, it left me rattled. It’s alarming to think what could have happened if I had been driving at that moment (especially since my car is currently out of commission). Had I not been driven to the clinic, I truly would not have been in a position to drive home myself. While some may question my experience, I firmly believe that it was the bright light directed at my eye that triggered this episode, though I remain uncertain about the exact reasons behind it.

It sounds like you had a distressing experience during your eye exam that was both physically uncomfortable and confusing. The symptoms you described—feeling faint, clammy skin, nausea, and disorientation—can indeed occur with bright lights, especially for individuals who have a history of migraines or light sensitivity.
Possible Causes
-
Light Sensitivity (Photophobia): Given your medical history with migraines and seizures, your brain may be more sensitive to abrupt changes in light intensity, which could trigger a sympathetic nervous system response. Symptoms like nausea and disorientation can sometimes arise from this.
-
Vasovagal Reaction: The combination of bright light and the stress of the exam might have caused a vasovagal response, leading to a sudden drop in heart rate and blood pressure. This can make you feel faint and nauseous.
-
Anxiety or Panic Symptoms: The experience itself might have caused anxiety, which can lead to physical reactions such as sweating, nausea, and a feeling of disorientation.
Prioritized Next Steps
-
Monitor Triggers: Keep a diary of your episodes. Note what activities, such as exposure to bright light or certain environments, seem to precede these reactions. This can help in identifying specific triggers.
-
Limit Bright Light Exposure: During any future eye exams or similar settings, ask the healthcare provider if they can adjust the lighting or if there's a way to minimize bright light exposure. Wearing sunglasses or visor during testing may also help.
-
Stay Hydrated and Calm: Ensure you're well-hydrated before any appointments and practice deep, calming breaths if you start feeling anxious.
-
Consult with a Specialist: If these episodes continue or worsen, consider discussing them with your doctor or a neurologist to rule out other potential causes related to your medical history.
-
Emergency Considerations: If you experience similar symptoms in other settings, especially while driving or engaging in activities that require full attention, it's important to prioritize safety by having someone with you or arranging alternative transportation.
It's understandable to feel rattled by this experience, especially since it seemed so sudden and intense. You're not alone in your feelings, and it's good that you reached out to understand it better. If you have follow-up questions or need more guidance, please feel free to ask.

28-Year-Old Male Experiencing Scalp Sensations Post-Amitriptyline Treatment
I am a 28-year-old man in generally good health, without any cardiac concerns. Approximately a month ago, I encountered intense pain localized to one side of my head, which was unresponsive to paracetamol. However, a single dose of a migraine treatment provided substantial relief. Following that, I began a regimen of amitriptyline, starting at a nightly dose of 10 to 25 mg. While my head pain has diminished significantly—by about 90 to 95%—I now experience occasional uncomfortable sensations on my scalp. These feelings include pins and needles, a cooling sensation, and some crawling feelings near my hairline and ears. There are fleeting moments where I feel brief throbs lasting a second, but I do not have any persistent headaches. To clarify, I do not experience any of the following: - Nausea - Weakness in my limbs - Numbness - Changes in my vision - Coordination difficulties - Seizures The symptoms I have are transient, shifting around and often intensifying when I become conscious of them or as the day progresses. I would like to know: Is it common to experience these sensations during the recovery stage following episodes of neuralgia or migraine-like discomfort? Additionally, could the amitriptyline potentially be causing these temporary paresthetic sensations? I am seeking some reassurance or advice on what is typically observed during this healing process. Thank you.

Battling Chronic Nausea and Vomiting for Over Two Years
For the past two years, I (age 26, female) have been enduring an incredibly challenging health situation. I experience intense nausea daily and find myself vomiting numerous times, with almost nothing providing relief. To provide some background, I’m from West Texas and I currently weigh around 190 pounds, standing at 5’7”. Initially, my weight was about 211 pounds when these symptoms began, and it fluctuates frequently between 190 and 225 pounds. I engage in vaping and consume THC. Previously diagnosed with hypothyroidism, my condition seemingly resolved, according to my healthcare providers. Additionally, I have polycystic ovarian syndrome (PCOS). I have consistently faced irregular bowel movements, with stools that are loose and sometimes appear to have mucus. Compounding my struggles, I've also suffered from migraines. I have had an IUD for over five years, experiencing two insertions of the Kyleena device. In December 2022, my battle with health took a severe turn when I was diagnosed with stage 4 Hodgkin’s Lymphoma, requiring chemotherapy treatment, specifically AVBD (Apologies for not recalling the exact medication names). By July 2023, I had fortunately achieved remission. However, after reaching remission, my vomiting worsened, transforming from primarily white foam to a mixture of 80% bile, any food I attempt to consume, and still white foam. This intense vomiting, accompanied by significant pain in my upper back, escalated to more than eight episodes daily by November 2023. At that time, THC seemed to be the only avenue for me to retain any food. During this tumultuous period, I consulted various doctors who, after confirming I wasn’t pregnant, attributed my symptoms to Cannabinoid Hyperemesis Syndrome (CHS). Immediately, I ceased THC consumption for over six months, yet the vomiting continued unabated. Each time, doctors would prescribe ondansetron, regardless of my claims that it provided no relief. I experimented with various diets recommended by medical professionals, but there were no improvements in my condition. Eventually, I obtained a referral to a gastroenterologist who intended to perform an endoscopy. However, the procedure was prohibitively expensive even with insurance, and thus was never conducted. This doctor also ordered blood tests to rule out several gastrointestinal disorders, such as Crohn's disease, Irritable Bowel Syndrome (IBS), and gluten sensitivity, but all results came back normal. Afterward, I had another appointment with a different gastroenterologist, but the doctor failed to meet with me. Instead, a nurse informed me that the doctor had merely recommended promethazine without conducting any tests or scheduling further visits. When I mentioned the possibility of gallbladder issues, the doctor laughed dismissively at my suggestion. Discussing my situation with my oncologist, he suggested that my heightened sensitivity to food odors stemmed from my chemotherapy experiences while I was working in fast food. While food smells indeed affect me, I'm primarily triggered by medical scents such as rubbing alcohol and cleaning agents. This ongoing ordeal has been overwhelmingly distressing. I now experience episodes of vomiting accompanied by bright red blood, presumably due to a throat tear. When I first encountered this troubling symptom, I consulted a doctor who appeared unfazed and prescribed a promethazine suppository, which does help but makes me extremely drowsy. My nausea persists nearly around the clock, often feeling as if there’s a heaviness in the upper part of my abdomen. I frequent urgent care facilities when my symptoms intensify, only to be met with minimal assistance since this is a chronic issue. Currently, I lack a primary care physician. Whenever I sought one, I encountered skepticism regarding my condition, with some healthcare professionals implying that I was exaggerating my symptoms. Though many physicians who do take my situation seriously seem baffled, I've lost count of the diverse medical experts I've consulted about these ongoing issues. If anyone has insight or suggestions, I would genuinely appreciate it. I can share my latest bloodwork results if that would be helpful—just let me know!
Understanding Tuberculosis Exposure Risk
A 26-year-old male, who neither drinks alcohol nor smokes, seeks to understand the implications of exposure to tuberculosis (TB). As an anesthesia technician, I became concerned after I encountered a TB-positive patient about a month ago. I had to enter the patient’s room several times to perform blood gas tests. On my first entry, I mistakenly wore my N95 mask incorrectly due to the hectic nature of attending to multiple rooms. From my research, it appears that TB is quite transmissible; direct exposure can pose a serious risk of infection. Transmission usually requires prolonged contact with an infected individual, particularly in a close or face-to-face setting. In this case, the patient was lying face down and appeared to be sleeping when I entered. I have already undergone testing for TB, but I am eager to deepen my understanding of the risks involved in these situations.
24M | Unexplained Fainting Incident
**Note:** I previously shared this story, but it was inexplicably removed. I’m a 24-year-old male without any medical diagnosis or prescription medications. While I do consume alcohol occasionally, I hadn’t been drinking before this happened. Around 3 a.m., I got up from bed to use the restroom. As soon as I began to urinate, I suddenly felt a wave of dizziness. The next moment I was aware of was regaining consciousness in the bathtub, startled awake by the sensation of something dripping on me—only to discover it was my own blood. This was my first experience with fainting. When I came to, confusion set in. I was disoriented and couldn’t comprehend why I was being dripped on while in what I thought was my “bed.” Strangely, I also imagined that I was lying on a collection of marbles (which I actually don’t own)—this turned out to be the shattered glass of my shower door lying around me. I’m uncertain whether I lost consciousness first and then fell, or if the fall caused my brief blackout. It took me a few moments to understand why I was in the bathroom at all. I’m not sure how long I was out; I only remember it was around 3 in the morning when I initially got up, and about the same time when I regained consciousness. I dialed 911, and the ambulance arrived promptly. They checked my vitals, performed an EKG and measured my blood sugar, finding nothing unusual. At the emergency room, they repeated the vital checks, conducted a CT scan, drew blood, and took x-rays—yet still no abnormalities were detected. I had several cuts on my face and left arm (curiously, this is the arm that would have been turned away from the door), along with bruising around my ribs. Since the incident, I’ve been suffering from headaches and pain in my ribs. I received stitches on both my face and arm. The nurse suggested I could have stronger pain relief, but I opted for just Toradol. They eventually discharged me, stating, "We’re unsure what caused this, but return if it happens again." What might have triggered such an incident? How can I safeguard against it reoccurring if they remain uncertain about the cause?
