Shoulder Lumps: Causes and Treatment Options - Dermatology

More Info

Shoulder lumps can arise from various causes, especially following an injury. Given your history of shoulder trauma two years ago, it's essential to consider several potential explanations for the lump you are experiencing.

1. Soft Tissue Injury: After an injury, the body may form scar tissue or fibrous tissue in the area, which can present as a lump. This is often benign and may not require treatment unless it causes discomfort or restricts movement.

2. Bursitis: Inflammation of the bursa, a small fluid-filled sac that reduces friction between tissues, can lead to swelling. Subacromial bursitis, for example, is common in individuals with shoulder injuries and can result in a noticeable lump.

3. Cysts: Ganglion cysts can develop near joints or tendons, often following trauma. These fluid-filled sacs can vary in size and may remain stable or fluctuate over time.

4. Lipoma: This is a benign tumor made of fat tissue that can develop in various locations, including the shoulder. Lipomas are generally soft, movable, and painless.

5. Rotator Cuff Injury: If you had a rotator cuff injury, the resulting inflammation or degeneration could lead to the formation of lumps or swelling in the shoulder area.

6. Calcific Tendinitis: This condition occurs when calcium deposits build up in the rotator cuff tendons, leading to pain and swelling. It can sometimes present as a lump.

7. Infection or Abscess: Although less common, an infection in the shoulder area can lead to swelling and the formation of a lump. This would typically be accompanied by other symptoms such as redness, warmth, and fever.

8. Tumors: While rare, both benign and malignant tumors can develop in the shoulder region. If the lump has changed in size, shape, or has become painful, it is crucial to seek medical evaluation.


Recommended Actions
1. Medical Evaluation: It is essential to consult with a healthcare professional, preferably an orthopedic specialist, who can perform a physical examination and may recommend imaging studies such as an ultrasound or MRI to assess the lump's characteristics.

2. Monitoring: If the lump is stable and not causing pain or functional impairment, your doctor may suggest monitoring it over time.

3. Physical Therapy: If the lump is related to soft tissue injury or bursitis, physical therapy may help improve shoulder function and reduce discomfort.

4. Medication: Non-steroidal anti-inflammatory drugs (NSAIDs) can help manage pain and inflammation associated with the lump.

5. Surgical Intervention: If the lump is determined to be a cyst, lipoma, or another condition that causes significant discomfort or functional impairment, surgical removal may be considered.

6. Follow-Up: Regular follow-up appointments with your healthcare provider are essential to monitor any changes in the lump and adjust treatment as necessary.

In conclusion, the lump on your shoulder could be due to various benign causes related to your previous injury. However, a thorough evaluation by a healthcare professional is crucial to determine the exact nature of the lump and to establish an appropriate treatment plan. Early intervention can help prevent potential complications and improve your shoulder function.
