Small Bump on Thigh

6/23/2025, 1:00:43 AMMale25-34

I am a 20-year-old male, standing at 6 feet tall and weighing 130 pounds. After returning home from work today, I discovered a small, painless bump on my thigh. It feels somewhat like a bubble beneath the skin, allowing for a slight movement in a circular direction, although it tends to maintain its original spot. It's worth mentioning that due to my occupation, the outer part of my thighs often gets pressed against a metal surface for a substantial part of my shift, which typically results in bruising or mild swelling. However, I've never experienced a small lump like this one, which is approximately 2 centimeters in diameter.

It sounds like you're dealing with a small, movable bump on your thigh, which can be concerning, especially when it's a new development. Based on your description, this bump could be a variety of things, such as a lipoma (a benign fatty tumor), a cyst, or a reaction from repeated pressure in your work environment. The fact that it's painless and movable is generally reassuring, but it's essential to monitor any changes.

Explanation

Bumps under the skin can arise from different causes, including:

  • Lipomas: These are non-cancerous growths made of fat tissue, usually soft, movable, and painless.
  • Sebaceous cysts: These result from blocked oil glands and can feel like small, round lumps beneath the skin.
  • Fibromas: These are benign tumors of fibrous tissue.

Since you've mentioned that your thighs get pressed against metal surfaces at work, this might also lead to localized swelling or irritation, which could contribute to the bump's appearance.

Next Steps

  1. Monitor the Bump:

    • Keep an eye on the bump over the next few weeks. Note any changes in size, shape, or firmness. Also, feel for any new symptoms like pain, redness, or warmth.
  2. Avoid Irritation:

    • Try to avoid further pressure or irritation on your thigh. If you can, adjust how you sit or use padding if needed during work.
  3. Take Pictures:

    • Document the bump with photos taken from the same angle over the coming days. This can help you notice changes more easily.
  4. Self-Care:

    • Ensure you're keeping the area clean and free from irritation. Good hygiene can help if it's a cyst.
  5. Know When to Seek Help:

    • If the bump grows larger, becomes painful, or if you have any accompanying symptoms such as fever, or if it doesn’t improve within a month, consider seeking further evaluation for a more detailed assessment.

Stay calm and monitor the situation. Most bumps like this are harmless, but it's always best to be vigilant about changes in your body. Let me know if you have any more questions or concerns!

INQUIRY REGARDING EYELID CORRECTION SURGERY

Hello everyone, I hope you're doing well. I want to share my situation regarding a drooping eyelid, which I developed due to an accident over six years ago. The droop is not overly pronounced, yet it becomes more apparent in photographs and catches my attention when I glance in the mirror. It gives the impression that one eye is somewhat smaller since the lid partially covers it. Fortunately, the condition has remained stable; it’s neither improved nor deteriorated. Could anyone tell me if there is a specific term for this issue? Additionally, I would like to inquire about the type of surgical options available for correcting a slightly droopy eyelid and what the potential costs might be. Thank you kindly for your assistance! I am 22 years old, 5'7" tall, weigh 130 lbs, and I’m a non-smoker who is not currently taking any medications.

TFCC Injury Concerns

About two and a half months ago, I (31-year-old female) had a fall where I landed on my outstretched arm. Since then, I’ve been experiencing ongoing discomfort on the side of my wrist that corresponds to my pinky finger. Any activities that involve bearing weight or twisting motions exacerbate the pain. Recently, I underwent an MRI examination, which revealed findings indicative of a low-grade strain. This included subtle thickening and swelling in the dorsal wrist capsule. Fortunately, the report confirmed that my triangular fibrocartilage complex (TFCC) remains intact, although there was a slight hyperintense signal that suggests early degenerate changes. I'm curious whether there might be other issues that were overlooked in the evaluation. I had some concerns about certain MRI images that seemed to show irregularities, although I acknowledge I could be mistaken.

Experiencing Warm Urine: Is It Normal?

I am a 26-year-old assigned female at birth and generally in good health. I do not smoke or drink alcohol, and I maintain a healthy weight. However, I do struggle with health anxiety. Currently, the temperature here is soaring at 100°F during the daytime and around 80°F at night, which often leaves me feeling overheated. Recently, I've noticed that my urine feels extremely warm, almost as if it were heated to a boil. I am curious whether this sensation could simply be a result of the high temperatures around me and my body temperature rising as a consequence, or could it indicate a more serious issue like a urinary tract infection, despite having no other symptoms or discomfort. It’s an odd feeling, but I’m hoping this is just a normal response to the heat.
