Strange Sensation in Chest (Urgent Attention Needed)
At 16 years old and weighing 115 pounds, I found myself seated when I unexpectedly experienced an intense and rapid heartbeat, accompanied by difficulty in breathing. My Apple Watch recorded two electrocardiograms, which I will share in the comments section. After this alarming episode, I attempted to stand and move around, but felt extremely lightheaded and ended up collapsing.

It sounds like you experienced a very concerning episode with your heart and breathing, which is understandably alarming. Intense and rapid heartbeat, difficulty in breathing, and lightheadedness, especially leading to a collapse, are symptoms that warrant careful attention.
Explanation
The combination of these symptoms can result from various causes, including anxiety, dehydration, a heart condition, or other medical issues. With your young age, it may be less likely to be serious, but it’s still critical to assess the situation, especially since you experienced a collapse.
Next Steps
-
Monitor Yourself: Keep track of any new or recurring symptoms over the next day or so. Note if you experience similar heart palpitations, breathing difficulties, or lightheadedness again.
-
Stay Hydrated: Ensure you are drinking enough water throughout the day. Dehydration can sometimes lead to these symptoms.
-
Rest: Take it easy over the next few days. Avoid strenuous activities until you can be seen by a healthcare provider.
-
Avoid Stimulants: Stay away from caffeine, tobacco, and other stimulants that may increase heart rate.
-
Use Your Apple Watch: Keep an eye on your heart rate using your watch. If you notice any significant changes or repetitive episodes, note those down.
-
Seek Professional Help: Given the severity of your symptoms, please consider seeking medical advice promptly, especially if these episodes continue or worsen.

Nervous About Visiting the Doctor as a Devout Christian
I apologize if what I’m about to share seems unclear, but I have been suffering from intense, persistent pain in my head for the past two months. The discomfort is so severe that I often find myself gritting my teeth to cope. I’ve been relying on over-the-counter medications, yet I believe I require a prescription to truly address this agony. Oftentimes, I am driven to tears because of it. As a devout Christian woman, I find myself apprehensive about the possibility of being harmed during my consultation. Currently, I do not have a doctor, as I have recently relocated, but as I search for a new healthcare provider, it is essential for me that they share my faith. Is it appropriate for me to reach out to the clinic to inquire about which doctors are Christians? I’ve been looking for information, but my efforts have led to frustration without clear guidance. I hope this doesn’t come across as unusual; rather, it’s a deeply concerning situation for me.
Can Topical Minoxidil 5% Accelerate Skin Aging or Lead to Collagen Depletion?
Research indicates that minoxidil, particularly at elevated levels, can hinder collagen synthesis. If this were accurate, it could potentially accelerate signs of aging. However, evidence suggests otherwise. A notable study examined the application of 2% and 5% minoxidil gel on burned skin in mice, effectively administering doses that were considerably significant relative to their body weight. The outcome? No observable alterations in collagen synthesis were detected. While it is important to acknowledge that this research was conducted on animals, it is crucial to apply critical thinking. Many studies highlighting collagen degradation also involve extremely high dosages or focus on human fibroblasts in laboratory settings with concentrations far exceeding those used in human applications. It is a well-known fact that any medication, when used at excessively high amounts, may produce negative health effects. Yet, topical 5% minoxidil is unlikely to affect collagen levels; if it did, any impact would be localized to the specific area of application. For me, the potential for my scalp to develop wrinkles is not a concern since it would be hidden under hair. It’s key to emphasize that there has yet to be conclusive evidence proving that low doses of minoxidil suppress collagen production in actual living human tissues. Instead, it may be wiser to focus on more prevalent side effects, such as swelling or cardiovascular issues that are associated with oral minoxidil usage. Some users have reported signs of aging but also noted improvements upon stopping the treatment, suggesting these experiences could be linked to an allergic reaction.

Lump Beneath the Armpit
I’m a 34-year-old male, standing at 1.71 meters tall and weighing 72 kilograms. For the past five to six months, I have noticed a lump in my armpit that has not gone away. Thankfully, it hasn't increased in size. My family doctor indicated that it could possibly be an ingrown hair and reassured me that it's likely not a serious issue. I have tried applying a cream called "Fucidine," but unfortunately, I haven’t seen any improvement. I would appreciate any insights or opinions you might have on this matter.
Understanding My Body's Quirks
I can’t quite disclose my exact age, but I've experienced this unusual phenomenon for as long as I can remember, and it’s undeniably strange. Recently, it seems to be happening more frequently—perhaps I’m just more aware of it now. So, here’s what occurs: whenever I feel chilly, get startled, or occasionally out of nowhere, my neck tends to jerk, usually leaning to the right, accompanied by a slight elevation of my right shoulder. Interestingly, as I was composing this message, I felt a similar reaction! I took a sip of a cold beverage and suddenly my entire left upper arm jerked upwards, and my neck tilted to the left. It’s quite puzzling!
Navigating Unexplained Symptoms: Seeking Guidance
Hello. Throughout my life as a young adult (aged 20-30), I have encountered various unusual health issues, particularly since entering puberty. Instances include an increased heart rate, skin eruptions that appear as small blood collections, randomly swollen legs, and sharply elevated liver enzymes (with ALAT levels peaking at 244 and ASAT well above 900 for a week before returning to normal). Despite undergoing a series of examinations at hospitals — including MRIs, ultrasounds, EKGs, and heart monitoring — no conclusive diagnosis has emerged. The only notable finding was a leaking heart valve, which the physician assured me is quite common and does not necessitate further attention, apart from the slightly elevated risk of a heart attack. Due to the sporadic nature of these issues occurring individually over the years, I have not given them much thought, particularly since nothing was deemed "seriously wrong". However, I now find myself contemplating whether these isolated episodes might be interconnected, particularly as they took place several years apart and did not recur frequently. Since August 25th, I have been experiencing bouts of dizziness in the mornings — episodes that cause temporary vision loss, nausea, cold sweats, and ringing in my ears, which generally subside after approximately 20 minutes of resting. These occur about twice a month. Overall, I often feel unwell, as if I have a lingering fever or cold, yet without a specific illness, alongside other minor issues that seem negligible. I am curious if there's a path forward to improve my quality of life. However, I also harbor fears that my concerns will be brushed off simply because I have been able to work and maintain an active lifestyle. My day-to-day existence is manageable, yet I frequently ponder how others feel upon waking — rejuvenated, healthy, and at ease? If you are a healthcare professional, how would you prefer to approach a patient with these concerns? Where would you recommend starting? How seriously should I regard these symptoms, given that they do not severely disrupt my routines? Is it even worth raising these points? What could potentially be the underlying cause?
