and Treating Persistent Bumps on the Big Toe: A Dermatology Guide - Dermatology

Skin issues


Hello, I have a small bump under my big toe that started in 7th grade.
It had a little bit of black in it, and out of curiosity, I cut it off with scissors, which resulted in continuous bleeding.
After the platelets healed the skin, another one appeared a month later, and I repeated the process of cutting it off.
I have done this three times, and it wasn't until 8th grade that I sought advice.
What is this bump? It feels very smooth and does not hurt.

Without actually seeing the lesion, it is impossible to determine the issue.
If it is very concerning, please seek medical attention as soon as possible.
A proper examination is necessary to understand the problem and to address it appropriately.

More Info


When it comes to persistent bumps on the big toe, especially those that have been present for several years and have been manipulated (such as being cut), there are several potential explanations and treatment options to consider. Based on your description, it sounds like you may be dealing with a type of skin lesion, possibly a dermatofibroma, a benign growth, or even a wart, particularly if there is a dark spot inside.
Dermatofibromas are small, firm bumps that can appear on the skin, often as a result of minor trauma or injury. They are typically harmless and may not require treatment unless they become bothersome or painful. Warts, on the other hand, are caused by the human papillomavirus (HPV) and can also appear as rough, raised bumps. They can sometimes have a dark center, which is often a collection of blood vessels.

Given your history of cutting the bumps, it’s important to note that this can lead to complications such as infections or scarring. Repeated trauma to the area can also cause the lesions to recur or become more pronounced. The fact that the bumps are not painful and feel smooth is a good sign, but it does not eliminate the need for a proper evaluation.

Here are some steps you can take to address the issue:
1. Consult a Dermatologist: The best course of action is to see a dermatologist for a thorough examination. They can provide a definitive diagnosis based on the appearance of the bumps and possibly a biopsy if necessary. This is crucial because self-diagnosing can lead to incorrect treatment.

2. Avoid Self-Removal: As tempting as it may be to cut or remove the bumps yourself, this can lead to further complications. It’s best to leave any removal procedures to a medical professional who can do so safely and hygienically.

3. Treatment Options: Depending on the diagnosis, treatment options may vary. If the bumps are dermatofibromas, they may not require treatment unless they are bothersome. If they are warts, treatments can include topical medications, cryotherapy (freezing), or laser therapy.
4. Monitor Changes: Keep an eye on the bumps for any changes in size, color, or shape. If they start to become painful, bleed, or show signs of infection (such as redness or pus), seek medical attention promptly.

5. Prevent Future Issues: To prevent future bumps, avoid trauma to the area. If you have a habit of picking at or cutting your skin, consider finding alternative ways to manage any underlying anxiety or curiosity that leads to this behavior.

In conclusion, while the bumps on your big toe may not currently be causing you pain, it’s essential to seek professional medical advice to ensure proper diagnosis and treatment. Avoid self-treatment methods, as these can lead to further complications. A dermatologist will be able to provide you with the best care and advice tailored to your specific situation.
