Unexplained Bump on Scalp: When to Seek Medical Advice? - Dermatology

I have developed a lump?


Hello doctor, in the past few days, I have developed an unknown lump on the scalp near my ear at the back of my head.
It is usually not painful, but there is tenderness when I press on it.
It does not appear to be particularly red or swollen, and it feels like a noticeable protrusion.
It seems to have something inside, but it is not fluid-filled.
I have researched online but am unclear whether it is a mass, a cyst, or an acne lesion.
Could you please advise if this can be identified or if I need to see a doctor? I am a bit anxious since it has been several days.
If it is necessary to see a doctor, I will go.
Thank you, doctor!

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 identify the problem and determine how to address it.

More Info


When it comes to an unexplained bump on the scalp, particularly one that is located near the ear and has been present for several days, it is important to approach the situation with caution and awareness. Based on your description, the bump is not particularly red or swollen, but it does cause pain when pressed. This could indicate a variety of conditions, and while some may be benign, others could require medical attention.

Firstly, it is essential to consider the characteristics of the bump. If it feels hard and has a distinct shape, it could be a sebaceous cyst, which is a common benign growth that occurs when a hair follicle becomes blocked. These cysts can sometimes become inflamed or infected, leading to tenderness and discomfort. On the other hand, if the bump feels more fluid-filled, it could be a lipoma, which is a benign tumor made of fat tissue. Both of these conditions are generally harmless, but they can cause discomfort and may need to be removed if they become bothersome.

Another possibility is that the bump could be a lymph node. Lymph nodes can become enlarged due to infections or other inflammatory processes in the body. If the bump is indeed a lymph node, it may indicate that your body is fighting an infection, which could be localized (such as a scalp infection) or systemic (such as a viral infection).
Given that the bump has been present for several days and is causing you concern, it is advisable to seek medical advice. A healthcare professional can perform a physical examination and may recommend imaging studies, such as an ultrasound, to better understand the nature of the bump. They may also inquire about any other symptoms you might be experiencing, such as fever, headache, or changes in your overall health, which could provide additional context for diagnosis.

In general, you should seek medical attention if:
1. The bump continues to grow or change in appearance.

2. You experience increasing pain or tenderness.

3. There are accompanying symptoms such as fever, chills, or night sweats.

4. The bump becomes red, warm, or starts to drain fluid.

5. You have any concerns about the possibility of skin cancer or other serious conditions.

In conclusion, while many bumps on the scalp can be benign and self-limiting, it is always better to err on the side of caution. Consulting with a healthcare provider will not only help alleviate your anxiety but also ensure that any necessary treatment is initiated promptly. Remember, your health and peace of mind are paramount, and seeking professional advice is a proactive step in managing your well-being.
