Knee Bump Concern
Approximately six weeks ago, I was engaged in a game of ball hockey when I received a strong blow to the outer side of my knee. This occurred directly on the tibial plateau, and since I wasn’t wearing any protective padding, the impact was quite severe. There was a minor cut that bled a little, but I was able to walk around for a couple of days without experiencing significant pain or my leg giving way. Interestingly, I attended a concert shortly after and felt perfectly fine with no discomfort. Recently, I’ve noticed a firm bump on that knee when I compare it to my other one. It gives the impression that there might be a small fragment of bone sticking out a bit. Based on my understanding, it doesn’t seem plausible that I have a fracture, as I would expect to be in noticeable pain if that were the case. I’m still capable of running, biking, climbing stairs, working out, and participating in other activities with no restrictions on movement or discomfort. The only time I experience a bit of pain is when I rise from the floor and place my weight directly on that area. It’s a sharp stinging sensation, but I manage to remain stable. I suspect this might simply be a significant bone bruise that is taking longer to recover, but I’d appreciate hearing additional opinions on the matter. Thank you!

It's understandable to be concerned about the bump on your knee after sustaining an injury. Given your description and the activities you can still perform without significant discomfort, it’s likely to be a benign condition such as a bone bruise, a soft tissue injury, or a localized swelling rather than a fracture.
Explanation: After a strong impact like yours, it’s common for the body to respond with inflammation and healing processes which can lead to swelling or bumps. The firm bump you feel could be due to several factors including:
- Bone bruise or contusion: This is a common consequence of trauma, where blood accumulates in the bone and surrounding tissues, leading to swelling.
- Bursitis: Inflammation of the bursa (a small fluid-filled sac) near your knee could also cause swelling.
- Possible small bone irregularities: Although rare, a hard bump might indicate some changes in the bone structure at the site of impact.
Since you have minimal pain and can perform activities without hindrance, it reduces the likelihood of a significant injury like a fracture.
Next Steps:
-
Monitor Symptoms: Keep an eye on the bump. If it starts to grow in size, becomes painful, or if you notice swelling that limits your movement, it would be important to take further action.
-
R.I.C.E. Method: When you experience pain, try the Rest, Ice, Compression, Elevation (R.I.C.E.) method to reduce swelling and discomfort.
- Rest the knee when feeling any pain and avoid activities that increase discomfort.
- Ice the area for 15-20 minutes several times a day.
- Use a compression bandage to help reduce swelling.
- Elevate your knee when resting to help with any swelling.
-
Gentle Stretching and Strengthening: As you’re still active, continue to gently stretch and strengthen the muscles around your knee, as long as it doesn’t cause pain. This can aid in healing and provide stability.
-
Avoid Pain Triggers: Pay attention to activities that cause pain, like rising from the floor. Modify your movements to prevent re-injury.
If you notice significant changes in symptoms, such as increased pain, swelling, or instability, consider seeking a medical evaluation for imaging if necessary. But for now, your approach seems well-directed toward monitoring and self-care. Let me know if you need more specific advice!

Interpretation Request for Recent Spinal NM Bone Scan
Hello, doctors. I'm reaching out for your insights regarding a recent NM bone scan of my spine. I've previously undergone a similar scan in 2022, and I'd like to compare the two. To provide context, I am a 29-year-old female weighing 100 kg, and I've been diagnosed with conditions including endplate sclerosis, spinal stenosis, cervical bone spurs, degenerative disc disease (DDD), and mild scoliosis. My medication regimen consists of several prescriptions. Unfortunately, my next appointment with my general practitioner is still a few weeks away, so I would appreciate your assessments on how the latest scan compares to the previous one. Thank you in advance for your help!
Unexpected Eye Issues: Headache and Double Vision Concerns
A 33-year-old female, measuring 1.67 meters in height and weighing 55 kilograms, residing in the Netherlands, experienced a sudden onset of symptoms. Last evening, shortly after dinner, my partner complained of a slight headache localized at the rear of her head. Along with this discomfort, she encountered double vision and noticed her right eye deviating outward. Interestingly, when she shut either eye, the double vision resolved, enabling her to see without distortion. We rushed her to the emergency room later that night. The medical team conducted a variety of assessments, including physical examinations, neurological evaluations, visual tests, and laboratory analyses. Fortunately, all results were normal. However, the doctors found it peculiar that her right eye exhibited normal movement and accurately tracked a pen in all directions when her left eye was closed. The medical opinion suggested that it may be a migraine-related episode, a condition she has experienced previously. Nonetheless, she insists that this feels unlike any migraine she has had in the past. A teleconsultation with a neurologist is scheduled for Monday to arrange an MRI should the symptoms continue. The doctors advised that if her symptoms worsen, we should return to the hospital immediately. Fortunately, after a night's rest, her vision had returned to normal by morning, the headache had subsided, and her right eye was aligned properly. I am understandably concerned, particularly due to her assertion that this does not resemble a typical migraine. Is it possible that this is indeed a migraine, or could it be indicative of another underlying issue? Thank you for your attention to this matter.

Intense Pain in Left Thumb
Greetings, I’ve been experiencing a piercing pain at the tip of my left thumb intermittently. This discomfort is situated within the thumb rather than on the outer skin. It primarily affects the underside of the thumb and surrounds the base of the nail. The pain seems to extend only to the first skin fold, specifically around the distal phalanx. When applying pressure, I’ve noticed some red streaks appearing beneath the surface, alongside the white area. I trust this explanation is clear. This issue has persisted for over a year, occurring sporadically but intensifying as time has passed. Could this be a cause for concern? A bit about myself: I am a 25-year-old female with no significant medical issues in my background. I previously smoked cigarettes for three years, transitioned to vaping, and have been vaping for six years now. I maintain an active lifestyle, frequently going to the gym and participating in various sports such as indoor football and pickleball. I don’t have any known allergies.
