a lump on my head, my breast is sore...

Hello and welcome to e health forum.

A lump in the neck can be due to multiple causes. The most common cause is a enlarged lymph node. Other causes can arise from soft tissue lumps, infective abscess, thyroid glands, musculoskeletal structures, etc.

Lymph node enlargement is a very common sign and can cause many people to get stressed and lose their sleep. A few major symptoms and danger signs can help you differentiate very common benign conditions from those indicating conditions like cancer and chronic diseases.

Symptoms like persistent fever, weight loss, night sweats along with multiple enlarged, painless lymph nodes may indicate conditions like lymphoma or cancer.

Smaller single nodes, that are tender to pressure without any other signs mentioned above can signify many common conditions including including upper respiratory tract infections, chronic infections like tuberculosis, local asymptomatic skin infections, etc.

You might consult a doctor for a physical examination and proper advise. In case of doubt, he might advise you to undergo a biopsy of the lymph nodes for a definitive diagnosis.

In the mean time, you can take Advil or Motrin , for a few days, and apply cold packs over the lumps. This measure, will help in resolution of your symptoms to some extent.
