Strange Sensation on My Knee: Carpet Burn Without a Mark
I'm a 30-year-old male experiencing an odd sensation in my knee resembling that of a carpet burn. Having encountered this feeling in the past, I was quick to recognize it. Curious, I pulled up my trouser leg to inspect, but there was no visible sign of irritation or injury. I palpated the area and discovered that the sensation had faded. However, whenever I apply pressure on my knee or it brushes against my trousers, the burning feeling resurfaces. This strange occurrence has persisted for about a week. It manifests similar to a genuine carpet burn, yet there are no marks whatsoever on my skin. I've even had others take a look, but I remain puzzled about what it could be and how to begin researching it. Any insights from those who might have an idea would be greatly appreciated. For additional context, I am slightly overweight, have no existing health issues, do not smoke, stand at 5 feet 7 inches, and am not taking any medication.

It sounds like you're experiencing a peculiar sensation in your knee that resembles a carpet burn without any visible signs on your skin. This could be due to several possible non-serious causes, such as nerve irritation, localized sensitivity, or friction from your clothing. Let's break down some common reasons for this sensation and discuss some manageable next steps.
Possible Explanations:
- Nerve Sensitivity or Irritation: Sometimes, nerves can become sensitive or irritated due to pressure or minor injuries. It may not show any physical signs, but the sensation feels quite real.
- Friction Dermatitis: This occurs when skin rubs against something hard or rough, even without visible marks. Clothing can cause this, especially if it's tight or abrasive.
- Mild Inflammation: Occasionally, underlying joint inflammation or bursitis can cause localized discomfort that may feel like a burning sensation, though this is often accompanied by swelling or pain.
Next Steps:
- Observe and Monitor: Pay attention to how the sensation changes throughout the day. Note if certain activities increase the discomfort, such as prolonged sitting or certain movements.
- Modify Clothing: Consider wearing softer, looser-fitting pants to minimize friction against the area. This may help alleviate the burning sensation.
- Gentle Care: Apply a cold compress to the knee when the sensation occurs to reduce any potential inflammation or irritation.
- Body Awareness: Engage in gentle stretching and strengthening exercises for the knee to ensure it maintains range of motion and muscle balance.
If the sensation persists or you begin to feel pain, swelling, or have any other concerning symptoms (like redness), it would be wise to seek further evaluation. Keeping a record of when the sensations occur and their intensity can be helpful for future reference.

It’s distinctly not acne or MRSA. We have tried injecting kenalog, but the growth returned within a week.

Understanding Your Mammogram Results
A 53-year-old female, measuring 5'6" and weighing 175 lbs, takes estradiol, a daily multivitamin, and a prebiotic. Additionally, she uses Flonase once daily to manage seasonal allergies. Her only notable health concern is mild asthma, for which an inhaler is utilized as needed, approximately once a week. Recently, she underwent a screening mammogram, which returned a result classified as "negative BI-RADS 1."

Should I Seek Medical Attention?
Recently, I experienced a tumble down a flight of stairs. Although the fall wasn't severe, my leg twisted beneath me, which caused me to slide. As a result, I now have quite a sizable bruise on my calf, resembling a large hematoma; the discoloration has made it appear rather unsightly, almost as if the skin is deteriorating. However, I'm not in any significant pain. I can walk without difficulty, apply pressure to my leg, and enjoy complete mobility. Having previously fractured my foot—not the same one that fell—on two occasions, I can confidently say this doesn’t feel comparable to a broken bone. The main issue is the swelling, which I'm currently managing by icing and keeping my leg elevated. Typically, I would rush to see a physician in circumstances like this, but considering I'm currently traveling in Japan, I'm uncertain about the appropriate steps to take. With a remaining 18 days left on my journey, I’m contemplating whether a doctor’s visit is necessary or not.
