Understanding and Preventing Fainting Episodes During Flights
I’m a 28-year-old male, weighing 135lbs, living with multiple sclerosis (MS) and tachycardia, which keeps my resting heart rate between 100 and 118 beats per minute. I've discussed this with my physician, but he hasn't shown much concern. I do have an appointment with a cardiologist scheduled for later this month for reassurance. Recently, hotter weather has significantly worsened my MS symptoms, leading me to consider that as a possible reason for my fainting episodes. However, during my recent flight, I experienced something quite alarming. I have nerve impairment and muscle weakness in my legs, which can lead to falls, but I’ve never fainted before. I had a decent breakfast at the airport about an hour prior, slept well, and hadn’t overexerted myself; apart from my usual discomfort, I felt reasonable. My partner and I boarded the plane, and shortly after takeoff, we encountered turbulence. I distinctly remember feeling dizzy and saying, "I feel dizzy," before losing consciousness and collapsing onto my partner’s lap. When I regained awareness, I felt lethargic, and my legs were unresponsive; my arms were tingling and beginning to feel numb. Despite my efforts to sit upright, I experienced another wave of turbulence and pressure changes a few moments later, feeling nauseous and lightheaded, followed by blurred vision and a heavy head. I lost consciousness again briefly, becoming limp. Throughout the rest of the flight, I leaned against my partner, trying to keep my head low, but since disembarking, I’ve felt uncomfortable and utterly drained. What might this suggest? I am uncertain whether I should contact my doctor or neurologist or if I should simply dismiss it. The thought of fainting during future flights terrifies me, particularly if I were alone and could have fallen onto a stranger. What strategies can I employ to avoid this situation altogether?

It sounds like you experienced a very concerning episode during your flight, especially given your existing health conditions. Fainting, or syncope, can be triggered by multiple factors, and it's understandable that you're anxious about it happening again. Let's break down what could be happening and how you can manage your situation better.
Main Points:
- Your fainting episodes might be related to the combination of turbulence, changes in cabin pressure, your MS symptoms, and possibly your underlying tachycardia.
- While you're already scheduled to see a cardiologist, there are immediate strategies you can employ to help prevent similar incidents in the future.
Explanation:
Fainting can occur when there's a temporary decrease in blood flow to the brain, often precipitated by stress, changes in posture, or environmental factors, such as heat or pressure changes during a flight. Given your multiple sclerosis, which can affect mobility and possibly increase fatigue, it's possible that the combination of sensations during turbulence could have triggered your symptoms. Nerve impairment and muscle weakness can also contribute to difficulties in maintaining blood circulation and responding to sudden changes, leading to feelings of dizziness and fainting.
Next Steps:
- Hydration: Ensure you’re well-hydrated before and during flights. Dehydration can worsen symptoms and increase the likelihood of fainting.
- Temperature Management: Dress in layers and consider light, breathable fabrics. Airplane cabin temperatures can fluctuate, and overheating may exacerbate MS symptoms.
- Seating Position: When sitting, aim to keep your legs uncrossed and your feet flat on the floor. If you feel dizzy, tilting your head down between your knees may help increase blood flow to your brain.
- Advance Notification: Inform your flight attendants that you have a history of fainting. They can assist if you experience symptoms again.
- Avoid Triggering Factors: Identify and reduce exposure to factors known to trigger your symptoms, like stress, sudden movements, or rapid flying conditions. If possible, plan flights at times when you usually feel your best.
- Symptom Diary: Keep a record of your symptoms leading up to and during flights. This can be helpful for discussions with your doctors and may reveal patterns or triggers.
Since you have a cardiologist appointment soon, it's a good opportunity to discuss these episodes and your concerns in more detail. Monitoring how you feel leading up to your appointment can provide valuable insights into your health and help improve your management strategies moving forward.
Take care, and I'm here to help if you have further questions or concerns!

Understanding Ear Crackling While Swallowing During Dehydration
I’m a 62-year-old male, standing at 183 cm tall and weighing 103 kg. I do not smoke, take no regular medications, and do not suffer from any significant chronic illnesses. Approximately fifteen years ago, I experienced a curious occurrence: whenever I find myself dehydrated, my ears begin to emit crackling or popping noises each time I swallow. Interestingly, after replenishing my fluids, this peculiar sound subsides almost immediately. Conversely, neglecting hydration inevitably leads to a headache within the hour. I’ve started to appreciate this phenomenon as a beneficial warning signal from my body, alerting me to hydrate before a headache manifests. Despite searching for others with similar experiences, I have yet to encounter anyone who faces this issue, nor have I discovered much information on the internet. Is it possible that the dry mucous membranes could be influencing the function of my Eustachian tubes? I would like to know if there is any existing knowledge regarding this occurrence and what its potential underlying causes might be.
Is It Time for a Check-Up or Am I Overreacting?
I’m a 37-year-old woman, standing 5’4” tall and weighing 160 lbs. This incident took place on June 20, 2025. At present, I am prescribed amlodipine, levothyroxine, and Lexapro. Here’s a condensed version of my unusual tale. While shopping, I accidentally struck my foot against an outdoor pallet loaded with landscape stones. It scraped just a bit and I quickly removed a small splinter that got lodged. However, the treatment used on those pallets caused intense burning pain—I felt shaky and nauseous afterward. The next day, my foot looked slightly swollen and had a pink tinge. Fast forward to a week later, and the swelling persists. It's a normal hue now, and thankfully, it hasn’t felt warm or shown any signs of infection. The painful area is near the cuneiform bone, just above the first metatarsal. Touching that spot is quite uncomfortable, and even wearing shoes and socks is a struggle. Deeper pressure also induces pain, making walking quite unpleasant. My husband advised me to seek medical attention, but I hesitate to go because living in a small town makes it feel as though I might be viewed as overreacting. You know how they say that women’s complaints are often minimized, often attributed to being overweight, hormonal, or anxious? I dread those visits! I barely tapped my foot, so I can’t comprehend the reason behind such intense pain and swelling. So, my inquiry is—what might be going on with me? Should I schedule a visit to the doctor, or am I being overly sensitive? I've included a comparison photo of both feet and a close-up of the affected area.
Over-the-Counter Solutions for Heartburn and Constipation

Rash Across Toddler's Body
An 11-month-old has developed a rash that initially appeared on her back nine days ago. This rash has significantly spread to her arms and legs, with a minor presence in the diaper area. By the seventh day, it made its way to her stomach, and only a tiny patch emerged on her cheeks. The rash produces moderate itchiness on her thighs and the back of her neck, although she otherwise seems relatively comfortable. Its texture is bumpy and rough. Notably, she hasn't experienced any illness recently. Since the onset of the rash, her bowel movements have become infrequent, and although she did have a bowel movement yesterday, it had a sour odor and a mucous-like appearance, which subsequently led to an itchy diaper rash. What could potentially be causing this? The pediatrician suspected eczema, while the dermatologist remained uncertain but suggested it might be scabies. However, a skin scraping did not reveal any mites, and no other household members are experiencing itchiness or a similar rash. Urgent care indicated it might be an allergic reaction. A follow-up appointment with the dermatologist is scheduled for next week to reassess the situation. The rash is not present on her scalp, palms, soles of her feet, or between her fingers and toes, but there are light patches on the tops of her hands and feet. I’ve applied hydrocortisone cream to reduce some redness on her thighs, which has helped. Does this appear to be scabies, or what else might it indicate?
Diagnosis of Cutaneous T Cell Lymphoma: What’s Next?
The situation has been confirmed as something other than a simple fungal infection. Following medical advice, my husband consulted with a dermatologist. Initially, she suggested a steroid cream, suspecting it might be eczema. However, with no improvement observed, she proceeded with biopsies of the affected area. During a follow-up visit to have his stitches removed, the dermatologist revealed the biopsy results. The diagnosis was Cutaneous T Cell Lymphoma, and she recommended him to a top specialist in the state who focuses on this type of condition. She mentioned that treatment could involve light therapy and expressed optimism by stating that the diagnosis was made early on. Interestingly, she refrained from using the term "cancer" throughout our conversation, which left me puzzled. When I researched it online, I found it categorized under blood cancers. So, my question is whether this diagnosis indeed constitutes cancer, or is it possible for this condition to be diagnosed at an early enough stage that it doesn't qualify as cancer yet? Despite his attempts to seek clarification, a response from the doctor may take a few days. He also scheduled an appointment with the new specialist, but they, too, indicated it might take some time to provide him with available dates. We are eager to understand how to move forward and gain clarity on what this diagnosis truly entails, especially concerning what the term "early stage" signifies in this context. My husband is a 39-year-old Caucasian male who was adopted. He does not smoke and has overcome alcohol dependency. He might be on Lexapro but is uncertain about his current medication regime.
