What Could This Unusual Long Red Mark on My Thigh Indicate? It's Been Present for Months
At 23 years old, weighing 190 pounds and standing at 5'1", I have a few health concerns, including obesity, orthostatic hypotension, tachycardia, and meralgia paresthetica affecting the same thigh where this mark is located. This peculiar red line emerged several months ago and has remained unchanged since then. It's slightly shorter than the length of my index finger and appears to have a similar texture to the surrounding skin. While I suspect it might have grown a bit since its initial appearance, I only started to notice it more closely this month. What could it possibly be?

It’s understandable to feel concerned about an unusual mark on your skin, especially when it has been present for several months. A persistent red mark like the one you describe can have several potential causes, including irritation, dermatitis, or vascular changes. However, given your health history and the specific characteristics of the mark, it’s important to take certain steps to understand it better.
Explanation
The red mark on your thigh may be related to several factors, such as:
- Skin Irritation or Dermatitis: This can occur due to friction, allergic reactions, or irritants. Given that you have meralgia paresthetica, which can lead to nerve issues in the thigh, irritation in this area might be possible.
- Vascular Changes: Sometimes, vascular issues can cause marks or discoloration, especially in the context of orthostatic hypotension.
- Other Skin Conditions: Certain conditions, like granuloma annulare or other benign skin lesions, can appear as red or discolored areas on the skin.
Since the mark has been present and seemingly changing over time, it is essential to monitor it closely for any changes in size, color, texture, or if symptoms such as itching or pain develop.
Next Steps
-
Document Changes: Keep a record of the mark’s appearance. Take photos weekly to track any changes in size, color, or texture. This documentation can be helpful.
-
Self-Care Measures:
- Avoid tight clothing that might irritate the area, especially considering your condition of meralgia paresthetica.
- Keep the area clean and moisturized to prevent any additional irritation.
-
Monitor Symptoms: Note any worsening symptoms such as increased redness, swelling, pain, or other systemic symptoms (fever, chills).
-
Seek Evaluation: If the mark changes significantly, starts to cause discomfort, or does not improve with time, consider seeking a professional evaluation to rule out any serious conditions.
Remember, while many skin marks are benign, paying attention and being proactive is important, especially with your existing health concerns. Feel free to follow up with any questions or updates!

White Lesion on Frenulum in a Toddler
Recently, I observed a white lesion on my 2-year-old son’s labial frenulum, which I believe is the tissue that links the lower lip to the gums. I’m curious to know whether this condition is typical, possibly indicating scar tissue from a past injury, or if it warrants a consultation with a medical professional. Any insights would be appreciated!
Identifying Oral Growth in a 9-Month-Old
I have a 9-month-old son who has developed a noticeable white growth in his mouth. Initially, we assumed it was a new tooth; however, it is clear that this is not the case. When we examined it, we found that it's soft to the touch, quite different from his emerging teeth, and the top part can actually move slightly. This growth seems to be emerging from his gums and is expanding at a rapid pace. We first noticed it on Tuesday, and it has already surpassed the size of his existing teeth. He appears unaffected by it—showing no signs of discomfort, fever, or issues with feeding. He still uses his pacifier without any problems. Does anyone have suggestions about what this could be?
Swelling in Left Foot
For the past two years, I have been experiencing swelling solely in my left foot, particularly affecting the top and my toes. I have consulted multiple doctors and undergone various tests and imaging procedures, yet none have provided any clarity. Occasionally, I notice a tingling sensation in my toes, and at times there is a subtle, aching discomfort. Is there anyone who might have insights into what could be causing this issue? I am a 49-year-old female, a non-smoker, standing at 5’7 and weighing 143 pounds. The only medication I consistently take is Premarin.
Understanding the Yellowish Brown Ring on the Penis
A 14-year-old male reports observing a yellowish-brown discoloration encircling his penis. He does not experience any discomfort and has noted that the ring feels similar to the veins on one’s wrist, albeit less pronounced.

Understanding Rising Platelet Levels in a One-Year-Old
I'm reaching out for thoughts or similar stories that you might have. My daughter, who is just over a year old, has had her platelet counts checked three times in the last four months, and they have shown a steady increase: - In February, her count was 511K, coinciding with her bout of norovirus. - By April, it reached 677K, during which she had a mild cold and also got her 1-year vaccinations. - In June, it further rose to 726K, at which point she was completely healthy and showed no signs of any illness. All other blood parameters, including her white blood cells, red blood cells, hemoglobin, and differentials, have consistently been within normal ranges. She's been developing well and has no signs of anemia or any immature cells, nor any other physical health issues. I'm trying to remain calm, but I can’t shake the feeling of concern regarding this continuous upward trend in her platelet counts.
