What should you know about painful lump between neck and shoulder?

This area contains the trapezius muscle, skin and fatty tissue, lymph nodes near the lower neck, and structures above the collarbone. A muscle knot or strain may hurt with movement or pressure. A boil, cyst, or inflamed skin gland may be tender and warm. A nearby infection can enlarge a lymph node.

[Head and Neck Cancer](/conditions/head-and-neck-cancer/), [Lymphoma](/conditions/lymphoma/), and [Thyroid Cancer](/conditions/thyroid-cancer/) can involve neck masses, but the presence of a lump does not show which condition, if any, is responsible. An examination is needed.

Track when you first noticed the lump and whether it changes with posture, shoulder movement, or recent illness. Avoid squeezing it. Arrange an appointment if it remains, grows, feels hard or fixed, or has no clear explanation. A clinician may inspect the skin, test neck and shoulder movement, feel nearby lymph-node regions, and choose imaging or sampling when appropriate.

Bring a list of medicines and mention recent infections, dental work, vaccinations, injuries, or unusual exertion. These details can help separate a local irritation from a deeper mass.

Seek urgent help for breathing or swallowing difficulty, rapidly spreading redness, severe swelling, or a high fever. Prompt assessment is also appropriate for unexplained weight loss, drenching night sweats, persistent hoarseness, arm weakness, or a lump that steadily enlarges.

Ask: Does this feel like muscle, skin, or a lymph node? Is it above the collarbone? Do I need imaging or a tissue sample? Which changes should I monitor?
