The hard lump behind the ear should be evaluated based on its location for further management.
From the description, it is likely caused by inflammation of the lymph nodes in the ear area, which typically does not require special treatment.
However, a small portion of the swelling could be a tumor or may result from deeper inflammation.
It is advisable to consult an otolaryngologist for further examination.

When it comes to changes in lumps or hard masses behind the ear, it is essential to understand the potential causes and concerns associated with these changes. The presence of lumps behind the ear can be attributed to various factors, including lymphadenopathy, cysts, infections, or even benign or malignant tumors.
Lymph nodes are small, bean-shaped structures that are part of the lymphatic system, which plays a crucial role in the immune response. The lymph nodes behind the ear can become enlarged due to infections, inflammation, or other underlying conditions. For instance, a common cause of swollen lymph nodes in this area is an upper respiratory infection, such as a cold or flu, which can lead to the lymph nodes reacting to the infection. In such cases, the lumps may fluctuate in size, being more prominent during the day and less noticeable at night, as the body’s immune response varies with activity levels.

Another possibility is the presence of sebaceous cysts or epidermoid cysts, which are non-cancerous lumps that can develop in the skin. These cysts can become inflamed or infected, leading to changes in size and tenderness. If the cyst becomes infected, it may present with redness, warmth, and possibly drainage of pus.

In some cases, more serious conditions, such as tumors, can also present as lumps behind the ear. While most tumors in this area are benign, it is crucial to monitor any changes in size, shape, or associated symptoms, such as pain, fever, or changes in hearing.

Given your observation that the lump changes from one to two during the night, it is advisable to consult with a healthcare professional for a thorough evaluation. A healthcare provider may perform a physical examination and may recommend imaging studies, such as an ultrasound or CT scan, to assess the nature of the lumps. Additionally, if there is any concern about infection or malignancy, further diagnostic tests, including blood tests or a biopsy, may be warranted.

In summary, while changes in lumps behind the ear can often be benign and related to common conditions like infections or cysts, it is essential to seek medical advice for a proper diagnosis and management plan. Monitoring the lumps for any changes in size, tenderness, or associated symptoms is crucial, and timely medical intervention can help address any underlying issues effectively. If you are experiencing discomfort or have concerns about the lumps, do not hesitate to reach out to an ear, nose, and throat (ENT) specialist or your primary care physician for further evaluation.
