Unusual Bumps: Hair Follicle Issues or Acne?

Strange pimple-like lesions?

Hello Doctor, today while washing up in the dormitory, I noticed that my thigh seemed a bit dark, and I initially thought it was dirt.
However, after washing, I realized it looked like there was hair or some kind of hair growing underneath.
When I touched it, it felt like small bumps, either pimples or acne, but there was also a hair that seemed to be stuck in it.
I wanted to squeeze it out, but after trying for a long time, I couldn't get it out.
I believe it's just a very short hair growing out.
I would like to know if it's common for acne to look like this.
My brother told me to leave it alone, saying it might be something that will resolve on its own, and that trying to force it out could lead to an infection.
Is that a good recommendation? Additionally, if I want to get this treated quickly, which specialist should I see? Thank you for your advice and response.

Hello, what you are describing seems to be folliculitis, which refers to the swelling of hair follicles due to blockage.
Normally, there is a fine hair present in the follicle, which is part of its normal structure.
Folliculitis on the face is commonly referred to as acne.
If the folliculitis is larger, it is often referred to as a "boil" in colloquial terms.
It is advisable to leave it alone for a while; you may notice some white or yellow discharge coming out, and it will gradually resolve.
Thank you for your question.

More Info

It sounds like you're experiencing some concerning symptoms related to unusual bumps on your thigh, which may be related to hair follicles or acne. Let's break down your situation and provide some guidance.

From your description, it seems that you have a small, raised bump on your thigh that appears to have a hair trapped within it. This could potentially be an ingrown hair, which occurs when a hair grows back into the skin instead of rising up from it. Ingrown hairs can lead to inflammation, redness, and sometimes even infection if not treated properly. They often present as small, raised bumps that can resemble pimples or acne.

Your brother’s advice to leave it alone is generally sound, especially if the bump is not causing you significant pain or discomfort. Squeezing or trying to extract the hair can lead to irritation, and as he mentioned, it could increase the risk of infection. If the bump is indeed an ingrown hair, it may resolve on its own as the hair eventually breaks through the skin or is naturally expelled.

However, if you notice increased redness, swelling, or pus, or if the bump becomes painful, it may indicate an infection, and you should seek medical attention. In such cases, a healthcare provider may need to drain the area or prescribe antibiotics if an infection is present.

In terms of what type of doctor to see, a dermatologist would be the most appropriate specialist for skin and hair-related issues. They can provide a thorough examination and determine the best course of action, whether it involves topical treatments, drainage, or other interventions.

To prevent ingrown hairs in the future, consider the following tips:
1. Exfoliation: Regularly exfoliating the skin can help remove dead skin cells that may clog hair follicles and lead to ingrown hairs.

2. Moisturizing: Keeping the skin hydrated can help maintain its elasticity and reduce the likelihood of hairs becoming trapped.

3. Proper Hair Removal Techniques: If you shave or wax, ensure you’re using proper techniques and tools. Shaving in the direction of hair growth and using a clean, sharp razor can help minimize the risk of ingrown hairs.

In summary, while it’s likely that the bump you’re experiencing is an ingrown hair, it’s essential to monitor it for any signs of infection. If it doesn’t improve or worsens, don’t hesitate to consult a dermatologist for a professional evaluation. Taking preventive measures can also help reduce the occurrence of similar issues in the future.
