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.

Strange Jelly-Like Substance Observed from Wound
I’m a 21-year-old female living with an auto-inflammatory condition known as hidradenitis suppurativa (HS). Recently, I've experienced a concerning issue with one of my wounds. This particular wound causes significant pain and excessive bleeding. However, whenever I attend to it, I tend to find this unusual jelly-like substance present within it. Interestingly, this phenomenon has only occurred with this one wound and not any of the others I have. The bleeding seems to persist until I manage to remove this jelly substance, after which it typically slows down and comes to a halt completely. I’m seeking insights into what this might signify so that I can effectively discuss it with my healthcare provider.
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?
Swelling Beneath My Chin Near the Jawline
18-Year-Old Male: I'm reaching out to any medical professionals who might provide insights into my situation. I've been using marijuana since I was 14, but now, at 17, I'm making an effort to stop and have been clean for 18 days. Recently, I've discovered an unusual swelling located just beneath my chin, behind my jaw. It causes some discomfort when I move, yet it doesn’t feel painful continuously. I'm somewhat anxious that this could be indicative of a more serious issue, especially considering it's positioned near my chin's lymph nodes. Any advice or information would be greatly appreciated as it might help alleviate my worry.
Challenges with Appetite and Discomfort While Eating — Difficulty in Gaining Weight
As an 18-year-old male, I find that I become satisfied after consuming rather minimal amounts of food. This situation presents a considerable challenge, particularly since I only need to have a standard breakfast, lunch, or dinner to feel completely satiated for the remainder of the day. My goal of increasing my weight has made this issue even more complicated. When I limit myself to one meal per day, I often face weight loss or an uncomfortable sensation of fullness that leaves me feeling sluggish. Opting for two meals makes me feel excessively bloated, distracting me from my daily responsibilities. Moreover, I suffer from an unusual issue with my throat, where almost any food I consume causes discomfort, as detailed in the list below. I have contemplated focusing on having just lunch while continuing my weightlifting regimen to maintain my current weight and gradually build muscle. What advice could you offer? Could there be an underlying cause for these symptoms? Lastly, would it be wise for me to consult a healthcare professional? Foods That Cause Discomfort: Bread, flour, pizza, fruits, sugary or starchy items, seed oils, chips, and essentially everything else. Foods That Are Tolerable: Rice, salads, chicken, fish, and vegetables. Overall Symptoms Include: * Quick satiety after normal meals * Challenges in gaining weight * Bloated and lethargic sensations when consuming more than one meal * Persistent throat sensitivity to a wide variety of foods
