Popping Sound on the Outer Side of My Left Knee
I am a 45-year-old man. Back in 2016, I injured my knee, and ever since, I've experienced a distinct popping sound on the outer side of my left kneecap when I extend it outward. Alongside this, I'm grappling with a sensation of instability; at certain angles, it feels as if my knee shifts, causing excruciating pain until it eventually settles back to a normal state. Lately, I've become increasingly aware of how I move my knee, and I fear that the situation is deteriorating.

It sounds like you're experiencing knee instability and popping sounds that are causing you concern, especially since this issue traces back to a previous injury. Knee symptoms like yours can have various causes, including issues with ligaments, tendons, or cartilage around the knee joint. It's important to address these symptoms thoughtfully.
Explanation: The popping sound you hear during knee movement could be due to several factors, including:
- Ligament or tendon issues: Past injuries can lead to changes in how these connective tissues function.
- Cartilage wear or damage: This can cause instability and pain.
- Muscle imbalances: Weakness or tension in the surrounding muscles can also lead to abnormal movement of the knee.
As you’ve noted a fear of worsening conditions, it's good to be proactive.
Next Steps:
-
Monitor Symptoms: Keep a detailed record of your symptoms over the next few weeks, noting when the popping occurs and what activities seem to trigger pain or instability. This will help you identify patterns and triggers.
-
Modify Activity: Avoid movements that cause pain or make your knee feel unstable, especially high-impact activities. Focus on low-impact exercises like swimming or cycling that can strengthen the knee without excessive strain.
-
Strengthen Surrounding Muscles: Incorporate gentle strengthening exercises for your quadriceps and hamstrings, which support the knee. Some examples include:
- Straight leg raises
- Hamstring curls
- Wall sits
-
Use Support: Consider using a knee brace or support when engaging in activities that might stress your knee. This can provide stability and help you feel more secure during movement.
-
RICE Method for Pain: If you experience flare-ups, remember the RICE method—Rest, Ice, Compression (using an elastic bandage), and Elevation to manage inflammation and discomfort.
-
Reassess Regularly: If your symptoms do not improve, or if they worsen (such as increasing pain, further instability, or difficulty walking), reassess your situation in a few weeks. At that point, consider a consultation with a healthcare provider specializing in sports medicine or orthopedics.
You are not alone in this, and taking these steps can help you manage your knee better while protecting it from further injury. Let me know if you need more details or specific exercises!

Seeking Advice on a Possibly Mild Skin Condition (Male in His 20s)
(Additional images shared in comments with varied lighting) For about a year now, I’ve noticed a crescent-shaped reddish mark on the inner side of my knee. It hasn’t shown any significant changes in size or appearance during that period. The area is slightly elevated, measuring around 0.5 to 1 mm, but it doesn’t itch or hurt at all. I’m curious if anyone has any insights into what this might be or if it warrants further evaluation. My initial thought is that it could be ringworm. I’m fairly certain it isn’t related to a tick bite, as I previously had one in close proximity that looked quite different.
Should I Consult a Doctor? Possible Covid or Flu Symptoms
Greetings! A week ago, I started experiencing a sore throat, and two days later, I noticed a slight cough. By Saturday, my voice became hoarse, and now, on Monday, I'm feeling generally unwell with body aches. While the sore throat is bearable, it lingers, and although I’m not having severe coughing spells, I am concerned because I’ve developed muscle soreness along with my voice issues after a week. Is this something I should be worried about? Currently, I don’t have a fever and haven’t experienced any night sweats or similar symptoms. Could these signs indicate a typical case of flu or Covid, or might they suggest another underlying issue? It's worth mentioning that I also struggle with anxiety, which may be contributing to the muscle discomfort I'm feeling. For context, I have a medical history that includes anxiety and acid reflux. I’m a 28-year-old male seeking some guidance on whether I should reach out to a healthcare professional.
Understanding Unusual Heart Sensations After Normal Cardiac Tests
Hello, fellow community members, I’m a 21-year-old male, standing at 5 feet 11 inches tall and weighing 93 kilograms. My physical activity includes hitting the gym once or twice a week, playing football every week, and averaging about 5,000 steps daily. However, I spend the majority of my time sitting at a desk, leading to a largely inactive lifestyle. I’ve been dealing with mild acid reflux (GERD) and am currently on medication for slight thyroid and cholesterol issues. In November 2024, I underwent a 2D echocardiogram, and the cardiologist reassured me that my heart was in good shape and there was nothing to be concerned about. Recently, though, I have started to notice unusual sensations with my heartbeat; they can be quite pronounced, sometimes feeling loud, heavy, or even faint. It's almost as if my heart rhythm varies in intensity—sometimes it feels heavy then light, and back to heavy again. Additionally, I’ve experienced some tightness in my chest during minimal activities, like standing or light movements, yet I managed to walk eight flights of stairs and play football without any severe symptoms or faintness. Due to these sensations, I recently underwent an ECG. Since the platform doesn’t allow image uploads, I’ll share the key findings from the report: - Heart Rate: 65 bpm - P Duration: 110 ms - PR Interval: 130 ms - QRS Duration: 100 ms - QT/QTc: 374/402 ms - P Axis: 61° - QRS Axis: 58° - T Axis: 54° - RV5/SV1: 1.338 mV / 0.954 mV - RV5 + SV1: 2.292 mV The interpretation was a sinus rhythm, indicating no significant abnormalities detected. Additionally, I have completed thyroid and lipid panels; my cholesterol levels were borderline, but I am now on medication to manage this. My primary concern continues to be these irregular sensations, which often feel like my heart is vibrating or beating in waves, especially noticeable when I lie down or shortly after eating. Thankfully, there is no chest pain, fainting, or shortness of breath, just a persistent sense of discomfort and anxiety regarding my condition. I have a few questions for anyone with experience or knowledge in this area: 1. Could these sensations be common even if both the ECG and echocardiograms came back normal? 2. Would it be wise to consider a Holter monitor to detect any irregular patterns? 3. Might this be linked to the vagus nerve or acidity issues? 4. Is there a possibility of early heart disease despite having clear test results? I would appreciate any insights from those who might have encountered similar issues or from healthcare professionals who have seen these symptoms before. Thank you for your help! 🙏
Understanding Urethral Duplication: What to Expect from Your Urologist
I’m a 17-year-old male who suspects he may have a partially duplicated urethra. Essentially, there’s an additional opening situated right next to the primary urethra, which I jokingly refer to as my "decorative urethra" since it serves no functional purpose. While some might classify this as hypospadias, I can confidently say it is not the case. My urinary tract appears to be correctly aligned; however, my meatus has an unusual division caused by the natural skin in that region, leaving the upper portion disconnected and closer to the dorsal side. Consequently, I believe that my actual meatus is smaller than typical. Up until now, I haven't shared this with anyone—my parents remain unaware, and no one ever told me that this abnormality might not be ordinary. The unique structure of my urethra has never received a formal diagnosis. Until I turned 16, I just assumed that all males possess two openings on their glands and never questioned this notion. Fortunately, I have not experienced any complications as a result. Based on my research, I suspect my urethral duplication corresponds to type IA. Now that I have a urologist—who I’m seeing for an entirely different medical concern—I'm eager to discuss this with him. My main inquiry is whether urologists have knowledge about this particular condition. If I bring it to his attention, will he recognize it for what it is? If there are any urologists reading this, is this a condition you are familiar with?
Unpleasant Odor After Intimacy and a Bleach Reaction
I’m a 33-year-old male, weighing 65 kg and standing at 170 cm tall. I haven’t smoked in over a year, my skin appears normal, and I don’t take any regular medications. For the past year, I’ve been experiencing intense body odor after sexual activity, regardless of who my partner is. This unpleasant smell lingers for several days, and no amount of showers seems to alleviate it. Additionally, when I clean my surroundings with bleach, the odor resurfaces even stronger, even though I use gloves to protect myself. I consulted with a dermatologist, who prescribed me a cream containing Clotrimazole and steroids, but it seems to have exacerbated the issue rather than providing relief. Recently, I lost my job as a result of this problem; my coworkers mentioned that they couldn’t tolerate being near me due to the odor.
