Skin Bumps: What Could They Be and Should You Worry? - Dermatology

Share to:

I hope the physician can respond~ Thank you?


Hello, doctor.
I would like to ask about some small, pimple-like bumps that have appeared on my hands, sides of my waist, and chest.
They have been present for about 4 to 5 months now.
They are not painful or itchy, and I can squeeze out some white substance from them.
What could this issue be? I was previously concerned about sexually transmitted infections, so I had blood tests done three times.
The last sexual encounter was in mid-August of last year, and I had tests done at the end of August, mid-October, and mid-December, all of which came back negative.
If the tests from mid-August to mid-December show no issues, can I be reassured? I am really worried and hope you can respond.
Thank you.

More Info


When it comes to skin bumps that resemble acne and have been present for several months without pain or itching, there are several potential explanations. Given your description, it sounds like you may be dealing with a condition known as sebaceous cysts or possibly folliculitis. Both conditions can produce small bumps on the skin that may contain a white, pus-like substance when squeezed.

Sebaceous cysts are non-cancerous lumps that can occur when a hair follicle or oil gland becomes blocked. They are typically painless and can vary in size. These cysts are filled with keratin, a protein found in skin, hair, and nails, and they can sometimes become inflamed or infected, leading to discomfort. However, if your bumps are not causing any pain or discomfort, they may simply be benign cysts that do not require treatment unless they become bothersome.

Folliculitis, on the other hand, is an inflammation of the hair follicles, often caused by bacterial or fungal infections. This condition can also lead to small, red bumps that may contain pus. While folliculitis can be itchy or painful, it can also present as painless bumps, especially if it is mild.
Since you have undergone multiple tests for sexually transmitted infections (STIs) and received negative results, it is reasonable to feel reassured about that aspect of your health. However, it is important to note that the presence of these skin bumps is not typically related to STIs, especially if they are not accompanied by other symptoms such as pain, itching, or unusual discharge.

To address your concerns about these skin bumps, here are a few recommendations:
1. Observation: If the bumps are not causing any discomfort, it may be best to monitor them for any changes. If they begin to grow, change in color, or become painful, it would be wise to consult a dermatologist.

2. Avoid Squeezing: While it may be tempting to squeeze the bumps, doing so can lead to irritation, infection, or scarring. It's best to leave them alone unless they are causing significant discomfort.

3. Skin Care: Maintaining good skin hygiene can help prevent further irritation. Use a gentle cleanser and avoid harsh scrubs or products that may exacerbate the condition.

4. Consult a Dermatologist: If you remain concerned about the bumps or if they change in appearance, it would be beneficial to see a dermatologist. They can provide a proper diagnosis and recommend treatment options if necessary.

5. Stress Management: Anxiety about health issues can sometimes exacerbate skin conditions. Engaging in stress-reducing activities such as exercise, meditation, or hobbies can be beneficial for both your mental and skin health.

In summary, while the presence of small, painless bumps on your skin can be concerning, they are often benign conditions such as sebaceous cysts or folliculitis. Given your negative STI tests, it is unlikely that these bumps are related to any sexually transmitted infections. However, if you have ongoing concerns or if the bumps change, seeking the advice of a dermatologist would be the best course of action. They can provide you with peace of mind and appropriate treatment if needed.
