Strange Episodes of Faintness
As a 24-year-old woman in good health with a background in college athletics, I generally maintain an active lifestyle, working out intermittently. Typically, my resting heart rate falls in the range of 66-75 beats per minute. However, during the week leading up to Christmas in 2025, I experienced a troubling incident. I woke up feeling significantly dizzy, which I mistakenly attributed to hunger. After preparing breakfast, I snacked to alleviate the worsening dizziness. While attempting to sit down and work on my laptop, I suddenly felt a wave of intense shakiness accompanied by a tingling sensation coursing through my body. While I can't be certain, I believe I may have blacked out during this episode, as the only memory I have is clinging to the back of the couch. I found it difficult to breathe, prompting me to use my inhaler before heading to the hospital. The medical staff diagnosed me with dehydration and referred me to a cardiologist for further evaluation. In January, I underwent an echocardiogram and wore a Holter monitor. On January 5th, just as I was settling down for the night, I awoke, startled, feeling unable to catch my breath. A quick glance at my Apple Watch revealed a heart rate of just 39. Struggling to breathe, I resorted to my inhaler but felt extremely shaky and dizzy afterwards, likely a side effect of the inhaler itself. After consuming some crackers and hydrating, I started to feel somewhat better and managed to fall asleep. The subsequent analysis from the Holter monitor registered as normal, as did the echocardiogram. Fast forward to February 5th, and I found myself yet again in bed, on the brink of sleep when a sudden tingling sensation shot through my body, leaving me breathless and trembling. My watch indicated a heart rate of 103. I used my inhaler again and walked around my apartment, which seemed to provide some relief until I ultimately vomited. I feel lost and unsure of what steps to take next. Any guidance would be invaluable.

It sounds like you're experiencing distressing episodes of dizziness, faintness, and difficulty breathing. Your past evaluations have not shown any significant heart issues, which is reassuring, but your symptoms warrant attention and a structured approach to understanding and managing them.
Explanation
The dizziness and faintness you describe, coupled with fluctuations in your heart rate, could be linked to various factors like dehydration, anxiety, or possibly even an asthma-related response. The tingling sensation and shakiness might also relate to low blood sugar or hyperventilation, particularly when you're anxious or have difficulty breathing. Since your heart tests are normal, and these symptoms seem to be episodic, it's essential to consider lifestyle factors that may contribute.
Next Steps
-
Hydration: Ensure you stay well-hydrated, as it's crucial for overall health and can help prevent dizziness. Aim to drink at least 8-10 cups of water a day, more if you're exercising or feeling unwell.
-
Nutrition: Monitor your meals to prevent low blood sugar. Regularly consume small, balanced meals and snacks that include healthy carbohydrates, proteins, and fats. This can help maintain your energy levels.
-
Monitoring Symptoms: Keep a diary of your episodes, noting the timing, triggers, symptoms, and any actions that help relieve them. This can provide valuable insights for your healthcare provider.
-
Breathing Techniques: Practice deep breathing exercises to help manage shortness of breath and anxiety. Techniques such as slow inhalation through the nose and prolonged exhalation through the mouth may be beneficial.
-
Gradual Position Changes: When getting up from lying or sitting, do so slowly to avoid sudden drops in blood pressure, which can contribute to dizziness.
-
Stress Management: Consider incorporating stress-relief practices like yoga, meditation, or light physical activity, which might help with both emotional and physical symptoms.
-
Follow-Up: Ensure you follow up with your healthcare provider to discuss these episodes in detail. Depending on your symptoms, additional tests like blood work or a comprehensive evaluation by a specialist may be necessary.
Reassurance
Your experience is understandably concerning, but many individuals deal with similar episodes, often finding that lifestyle adjustments and anxiety management contribute to their improvement. Remember to be patient with yourself as you work towards understanding and managing these symptoms. Please let me know if you need further information on any of these steps!

Could my eardrum be damaged?
I’m a 34-year-old female with no significant medical history. Yesterday, I experienced a sensation of fullness in my left ear, which also affected my hearing. In an attempt to alleviate the discomfort, I applied hydrogen peroxide the previous night. However, this led to an increase in pain intensity. From approximately 10 PM until 2:30 AM, the pain became unbearable. I tried taking Tylenol and ibuprofen, but they didn’t seem to provide any relief. I continued to experience sharp, painful popping sounds. This morning, while the discomfort has lessened significantly, I still feel some pain and a noticeable reduction in hearing in that ear. I captured some images with an otoscope that I will share in the comments. Should I seek treatment at urgent care?
Understanding Phleboliths: What You Should Know
As a man in my late 30s, I’ve generally enjoyed good health without any significant concerns. However, following a recent CT scan, I was relieved to receive a report confirming that everything appeared normal. Out of sheer curiosity, I decided to obtain the images from the scan for a closer look. To my surprise, I spotted small white dots in the pelvic region, which I later discovered were identified as phleboliths. This raises a question in my mind: why weren't these mentioned in my report? Are they considered harmless? Currently, I’ve been experiencing a feeling of tightness and dull pressure around my navel. Medical professionals have suggested that I am exhibiting symptoms of abdominal muscle guarding, which I can recognize in myself. I'm left wondering if these phleboliths have any connection to my discomfort or if they are simply benign findings unrelated to my symptoms.
Unusual Yellow Growth on Eyelid

While examining myself in the mirror, I noticed an unusual protrusion from my eyelid. I lifted my eyelid's outer edge, only to be startled by what I found. Initially, I believed it could be the typical yellowish discharge often seen after sleeping. I attempted to wipe it away with a tissue and gently brushed it, but it wouldn't come off. Could anyone provide insight into what this could potentially be?
Persistent Wrist Pain One Month After IV Insertion
I’m a 29-year-old woman weighing 160 pounds, with no history of medical issues; I don’t use medications, smoke, or drink alcohol. Recently, I was admitted to the hospital where they inserted an IV in my wrist, just above the thumb. The nurse was quite forceful during the insertion, which resulted in a bit of discomfort, but I attributed that to the IV itself. There were no signs of infiltration, and I did observe blood return. However, since that time, I've been experiencing pain in the same area and slightly further up my arm. This discomfort has not improved at all. Even something as simple as holding a water bottle causes significant pain, making daily tasks like washing dishes challenging. Given that I’m pregnant and due to have a baby in a few months, I'm anxious about whether I’ll struggle to hold my child. I’m aware that pregnancy limits my activities, but I’m seeking reassurance or potential explanations for my symptoms. I’ve been using a wrist brace, which seems to offer some relief—though when I take it off, the pain often intensifies, perhaps due to lesser movement. I used to wake up with considerable pain after sleeping awkwardly on my wrist. Should I continue using the brace, or would it be better to move my wrist more frequently?
Query About Post-Surgery Recovery
I underwent a sistrunk procedure about four to five days ago. Thankfully, there were no issues during the surgery, and I was allowed to return home the following day. I received guidance to maintain the tape over the incision and to gently pat it dry after taking a shower. However, I've noticed that the tape has started to peel off despite my best efforts to follow these instructions. In response, I applied some skin color strips from the pharmacy. Unfortunately, I observed that more of the tape came off this evening, and the appearance of the wound surprised me. The left side, which corresponds to the right in my photo, seems more red and raised compared to the rest of the wound. As someone without a medical background, I’m curious to know whether this is a normal part of the healing process or if it warrants further evaluation. Overall, I have been feeling relatively well and have been managing any pain with paracetamol as needed. I have a follow-up appointment with my surgeon in three days. I am a 38-year-old woman, with pre-existing conditions including reflux and anxiety that is primarily health-related. Currently, I take paroxetine and esomeprazole every day.
