Understanding Twisted Tendons Behind the Knee: What Just Happened?
Greetings! I'm a 31-year-old male weighing in at 117 pounds, and I'd like to share an experience I had with my knee. Forgive the lengthy explanation; it’s been an ongoing issue. Recently, while I was laying sideways in bed with my knees bent, I attempted to roll over to stand up. During this movement, I experienced a sharp sensation in the back of my right knee—where my weight was concentrated. Immediately, I paused at the edge of my bed. After the incident, the area behind my knee felt somewhat numb and bending it felt unusual—as if something were out of alignment. I thought that by fully bending my knee, it might correct itself, but that didn’t yield any result. I then cautiously extended my leg, registering some resistance throughout the movement, but fortunately, no pain. Suddenly, I felt a release as something shifted back into place behind my knee. Interestingly, this adjustment wasn’t painful, but I sensed a definite movement. Once it was back in place, my leg returned to normal functionality; I was able to bend it comfortably, walk, and resume regular activities. However, there was some soreness behind my knee for a couple of hours after the incident, leaving a slight tenderness. This particular occurrence is not entirely new to me. A few years back, I frequently experienced similar issues when sitting awkwardly, often with my legs crossed. When I would stand up too swiftly, my knee would get 'stuck' during extension, mirroring today’s experience. If memory serves right, these instances have always involved my right leg, and I’ve been able to remedy it each time by bending and straightening until it felt right again. Interestingly, this started when I was completely sedentary but seemed to fade after I incorporated exercise into my routine. That said, I sustained a lower back injury about a month ago, which halted my leg workouts for a while, and, coincidentally, this morning it happened again. I’m reaching out to inquire if anyone can shed light on what occurred and whether this could pose a problem for me down the road if it persists. My online searches reveal discussions mostly about more severe injuries that require interventions like physical therapy or even surgery, which I don’t feel apply to my case. I am hopeful that returning to my leg workouts will alleviate these issues once more. Any insights would be greatly appreciated!

It sounds like you've experienced a concerning but often manageable issue with your knee, likely relating to the soft tissues or structure around your knee joint, such as tendons or ligaments. Given your description, it appears that what you experienced may have involved a temporary misalignment or impingement that corrected itself through movement. Here's what you need to know:
Overview
The sensations you felt behind your knee—sharpness, numbness, and a subsequent release—might indicate a type of soft tissue injury or joint irritation that can occur from awkward positioning or sudden movements. Such occurrences can happen when tendons or ligaments are stretched or compressed, especially if you've recently reduced physical activity due to your back injury.
Explanation
- Soft Tissue Issues: The back of your knee (popliteal area) contains tendons and ligaments. When you're in a position for an extended period, such as sitting with your legs crossed, these structures can become tight or compressed.
- Movement: When you tried to straighten your knee, you may have shifted these structures back into their proper alignment, alleviating the pressure and discomfort.
- Previous Patterns: Your past experiences of having the knee “get stuck” suggest a recurrent issue, possibly due to tendon laxity or a minor mechanical instability that usually resolves as you learned to adjust positions.
Next Steps
To manage and potentially alleviate these occurrences, consider the following prioritized actions:
-
Gradual Return to Exercise: Since you noticed improvement after incorporating exercise, resume light leg workouts while taking care to avoid aggressive movements that may stress the knee. Focus on range-of-motion exercises and strengthening the muscles around your knee.
-
Stretching and Strengthening: Include stretches for your hamstrings, quadriceps, and calves, which can help maintain flexibility and reduce strain on your knee. Incorporate gradual strengthening exercises to support joint stability.
-
Monitor Symptoms: Keep an eye on changes in your knee. If you experience repeated sensations of “sticking,” increased pain, swelling, or reduced mobility, consider modifying activities and resting when necessary.
-
Position Modification: Avoid awkward positions for long periods (like sitting cross-legged) and be cautious when transitioning between sitting and standing.
-
Consult with a Professional as Needed: If episodes become frequent or if you notice significant pain or instability, consider consulting a physical therapist or healthcare provider for tailored advice and potentially a further assessment.
Your awareness of your body and proactive approach to fitness are significant assets in managing this situation. Stay mindful of your symptoms, and with a gradual return to exercise, you may improve stability in your knee. Let me know if you have more questions or need further assistance!

Unexpected Knee Discomfort Five Years Post-Replacement
As a 65-year-old woman, I underwent knee replacement surgery five years ago and experienced a smooth and uncomplicated recovery. However, three days ago, I began to notice some troubling symptoms: my knee felt stiff and showed signs of swelling. Unfortunately, the situation has deteriorated; my knee is now buckling and I am experiencing significant pain while standing. The inner part of my left knee is particularly tender to the touch. I haven't suffered any injuries that could account for these issues, but I do feel generally unwell with symptoms including a headache, body aches, and a bit of diarrhea. I'm curious about what might be causing these problems. I have a doctor's appointment scheduled for Friday, but I’m questioning whether I should seek immediate help at urgent care instead.
Concern Over Lost Septum Ring Ball
I’m a 22-year-old and I’m a bit unsure where to share this, but I hope it’s not too silly of a question. I wear a septum ring and usually keep it flipped up for work. However, yesterday I had it turned down all day and found myself sneezing frequently. Initially, I attributed it to allergies, but it felt as though there was something irritating my nasal passages that prompted the sneezing. Today, when I switched my septum ring back to its normal position, I realized that one of the balls was missing. Now I’m anxious it might have lodged itself inside my nose. Is it possible for it to travel down my throat and pass through my system, or should I consider consulting a medical professional?

Additionally, I maintain a healthy weight. However, due to my significant anxiety regarding health issues, I find myself reluctant to reach out to my physician about these bothersome symptoms. Can anyone provide insights on the potential causes of these ongoing occurrences? Should I consider contacting my doctor regarding this matter? I appreciate any guidance.
Chest Rash Following Influenza A in My Daughter
Hi, I would like to share my experience with my five-year-old daughter, who weighs 45 pounds and recently battled Influenza A. Over the past week, she experienced significant illness, enduring high fevers that persisted for about six days despite treatment. Thankfully, her fever finally decreased yesterday, and she appears to be on the mend. However, she has now developed a rash on her chest and seems to be exhibiting increased fatigue. Is this a typical response following a bout with the flu?
Struggling with Dental Issues: Seeking Guidance
Acknowledging this situation is quite challenging for me. To begin with, I reside in the UK, where the National Health Service (NHS) provides dental treatments at no cost. However, there tends to be an extensive waiting list for appointments, and I lack the funds for private care. As a 22-year-old woman, I experienced significant neglect during my teenage years. This neglect led to a deep depression, resulting in lengthy periods where I neglected oral hygiene, indulged in excessive sugary snacks, and unhealthy foods. My mother did not take me for dental visits, nor did she offer guidance on proper oral care beyond the simplistic instruction of 'brush your teeth.' Eventually, I was removed from the dentist's roster. While I no longer struggle with depression, the consequences of my past actions have emerged. One of my teeth has gradually deteriorated to the point of complete loss. In case someone wonders why I didn’t seek dental help sooner after noticing the initial damage, the answer lies in my crippling anxiety and embarrassment. I felt so hopeless at one stage that I questioned my own existence, leading me to suppress my concerns about my dental issues. Now, with that tooth completely gone, I fear I may have additional cavities. I often notice my gums bleeding during brushing, and I’m terrified of the possibility of developing an infection that could lead to severe health complications. However, the thought of visiting a dentist fills me with dread. I feel lost about the steps I need to take. I don't have anyone to confide in regarding this matter, which makes me feel I need to isolate myself until I resolve this issue. It’s a back tooth, so it’s not immediately visible, but I worry that if I grow close to others, they'll notice or infer what’s happening. I know I need to take action. Should I consult an emergency dentist? Is it necessary to experience pain to seek help? I’m reaching out to anyone who might have insights or suggestions on how to proceed with this situation.
