The neck contains many lymph nodes, which are part of the body’s immune system. When those nodes become inflamed or affected by disease, such as lymphoma, itching can occur — sometimes without any visible skin irritation.
Lymphoma-related itching tends to be deep, persistent, and hard to relieve. If you’ve ruled out allergies, skin products, and clothing irritation, and the itch continues, it’s time to speak with your doctor.
What to watch for: Night sweats, unexplained weight loss, fatigue, or noticeable swelling in the neck or armpits.
