Is This Noise Typical?
For approximately a year, I have been experiencing occasional discomfort in my left knee. It produces a rather alarming sound when I bend down, though I've always had a tendency for my knees to crack. At 30 years of age, I engage in running and weightlifting, and I maintain a healthy body weight without any known health issues. I have been reluctant to consult a physician regarding this problem since I am uncertain if it truly qualifies as a concern, and if so, whether any effective treatment options are available. I apologize for the less-than-ideal quality of the video; capturing the sound of one knee while squatting is quite challenging.

The sounds you’re hearing from your left knee while bending, especially if accompanied by discomfort, warrant attention. While it's common for knees to make noises like popping or cracking—often related to movement of ligaments or tendons—ongoing discomfort might suggest an underlying issue. It’s good that you maintain an active lifestyle, but it’s important to address any pain to prevent potential worsening.
Explanation
Knee noises can result from many factors, including:
- Tendons or Ligaments: As you bend and flex your knee, these structures might catch or snap over the bones.
- Cartilage: Injuries or degeneration to the cartilage (like runner’s knee or patellofemoral pain syndrome) can lead to both noise and discomfort.
- Overuse: Activities like running and weightlifting can put stress on your knees, especially if form or footwear is inadequate.
Next Steps
-
Self-Assessment: Begin by monitoring your knee. Note if the discomfort persists, increases, or is accompanied by swelling, instability, or locking.
-
Activity Modification: While ensuring you’re still active, consider reducing high-impact activities that might strain your knee. Substitute with low-impact exercises (like cycling or swimming) that keep you fit without excessive joint stress.
-
Strengthening & Flexibility: Work on strengthening the muscles around your knee (like the quadriceps and hamstrings) and improving flexibility. Simple exercises like straight leg raises, step-ups, and stretching routines can be beneficial.
-
Rest & Ice: If you experience discomfort after activity, consider resting your knee and applying ice for 15-20 minutes to manage any swelling.
-
Footwear Check: Ensure that your shoes, especially for running, provide adequate support. Poor footwear can greatly affect knee comfort.
If symptoms do not improve in a few weeks or worsen, consulting a healthcare provider, preferably a physical therapist or orthopedic specialist, would be wise. They can provide a more tailored evaluation and develop a rehabilitation plan if needed. Remember, addressing early signs of discomfort can help maintain your active lifestyle.

Seeking Recommendations for a Specialist to Repair a Full-Thickness TFCC Tear in the United States
I'm a 25-year-old female and I’ve been dealing with a wrist injury for the past ten months. Yesterday, I had an arthrogram MRI done to get more clarity on my situation. If you were in my shoes and needed to restore your strength and dexterity, which doctor would you choose to trust for your wrist specialist? I'm open to traveling anywhere in the United States for the right care. About ten months ago, I had a serious incident where a horse kicked me in the chest while I was holding a lead rope in my left hand. There’s a possibility that the horse's back hoof made contact with my left hand, but I can’t be certain. I ended up with a fractured right scaphoid, but surprisingly, the pain and discomfort in my left wrist (which wasn’t fractured) were at least as severe, if not worse, than my right. The swelling and bruising I experienced were considerable. After being referred by the emergency room to a hand surgeon, the focus was predominantly on my scaphoid fracture. They did take some images of my left wrist and diagnosed me with tendonitis. It was only about a month ago that I consulted a second physician who suspected a TFCC tear. Fast forward to yesterday, when I finally managed to undergo an arthrogram MRI for confirmation. Regaining full function is paramount to me, not just physically but also for my mental and emotional wellbeing. I’m keen to gather multiple perspectives on possible treatment plans. If you were facing the same situation and it was your wrist on the line, where would you seek help? Who would you trust to ensure a successful outcome?
Exploring Causes: Vasovagal Response, TIA, or VAD?
I’m a 21-year-old male, currently taking a daily dose of 25mg losartan, standing at 5'9" and weighing 300 pounds. As part of my routine, I often walk about 9,000 steps each day. On September 9th, while clocking out at work, I engaged in my usual habit of looking up at the ceiling and shrugging. At that moment, I heard the familiar popping sound from my neck and upper back—something that frequently occurs for me during routine movements like turning my head or even taking a deep breath. Immediately following this neck adjustment, I experienced a peculiar shiver, which led me to think, "Oh no." Shortly after, I felt a wave of warmth starting from my chest, radiating toward my head. My vision became hazy, and I sensed a lightheadedness as though I might faint or lose consciousness. It felt like I was not getting enough oxygen, making it difficult to breathe, and my palms began to sweat. Thankfully, all these sensations subsided completely in just under two minutes. During this unsettling period, I was still engaged in conversation with a colleague, responding with casual remarks like, "Uh huh, sure." The episode echoed some of the panic attacks I’ve had in the past, albeit somewhat more intense. I considered stepping away to splash water on my face or sit down, but I ultimately felt fine as everything settled down quickly, and I did not experience any lingering symptoms. As of September 12th, I have resumed my normal activities—working, eating well, sleeping, engaging in intimacy, assisting in pushing a heavy car in neutral, and climbing stairs without issues. I've even replicated the neck motions that prompted the incident without experiencing the same distress. I consulted a friend who works as a medical examiner, and he suggested it might have just been a Vasovagal response. However, online resources raise concerns about more severe conditions like VAD or TIA, while my family leans toward attributing it to anxiety. In summary, on September 9th, a neck pop occurred while looking up and shrugging, which led to feelings of lightheadedness, warmth, blurred vision, sweaty palms, and a sensation of insufficient air, all vanishing within two minutes and accompanied by no neurological issues.
Concerns After Two Weeks of Vaping: A Personal Experience
At the age of 16, I recently tried vaping for a couple of weeks while hanging out with friends. Although I don’t find it enjoyable and don’t feel addicted, I started experiencing shortness of breath and chest discomfort. Concerned about my symptoms, I scheduled a visit to my doctor. After conducting a check-up, which included assessing my vitals and listening to my heart and lungs, the doctor assured me that everything appeared to be normal and within acceptable limits. Despite the doctor's reassurances, I’m feeling anxious about my health. However, I’ve been maintaining a balanced diet and staying active, which leaves me uncertain about the seriousness of my situation. One thing is for sure: this experience has made me decide never to vape again!
Is There an Infection at My Tooth Extraction Site?
Height: 5'4", Weight: 168 lbs, Age: 26, Non-smoker, Occasionally consumes alcohol. Hello everyone, I underwent the extraction of a lower molar two days ago (09/10 at 11 AM).

My jaw is still quite tender. Is the healing process for my extraction site going as it should?
