What could a hard bony lump on my left collarbone be that causes trouble breathing at night?
A hard bony lump on your left collarbone that causes trouble breathing at night could be a sign of a number of underlying medical conditions. It is important to see a doctor to get a proper diagnosis and treatment. Some possible causes of this symptom include:
1. Clavicle Fracture: A fractured clavicle, or collarbone, can cause a hard bony lump to form at the site of the break. This can lead to pain, swelling, and difficulty breathing, especially when lying down.
2. Osteosarcoma: Osteosarcoma is a type of bone cancer that commonly develops in the long bones of the body, including the clavicle. It can cause a hard, painful lump to form, along with other symptoms like fever, weight loss, and fatigue.
3. Metastatic Cancer: Cancer that has spread from another part of the body to the clavicle can also cause a hard lump. This is known as metastatic cancer. Common primary sites for cancers that spread to the clavicle include the lungs, breast, and prostate.
4. Infection (Osteomyelitis): A bacterial or fungal infection of the clavicle can cause inflammation, leading to a hard, swollen lump. This condition, known as osteomyelitis, can cause pain, fever, and difficulty moving the affected arm.
5. Sternoclavicular Joint Issues: Problems with the sternoclavicular joint, where the collarbone meets the sternum, can also cause a hard lump and breathing difficulties. This can include conditions like sternoclavicular joint dislocation or arthritis.
6. Subclavian Vein Thrombosis: A blood clot in the subclavian vein, which runs along the collarbone, can cause swelling, pain, and a hard lump in the neck and upper chest. This can also lead to shortness of breath and difficulty breathing.
7. Lymphoma: In rare cases, a hard lump on the collarbone can be a sign of lymphoma, a type of cancer that affects the lymphatic system. This can cause swelling in the lymph nodes, including those located near the collarbone.
It is important to see a doctor for proper evaluation and diagnosis of the hard bony lump on your collarbone and its associated breathing problems. The doctor may recommend imaging tests, such as X-rays or MRI scans, to determine the cause and provide appropriate treatment.
