What causes a pea sized lump below the collarbone?
Patient: I have a small, hard, pea sized lump below my collarbone up close to where it meets up with my shoulder.  It doesn't hurt or anything.  It doesn't really move much either, maybe a very small amount but it seems pretty stationary.  Should I be worried? Doctor: Hi,The lump is usually a lymph node or rarely a lipoma. If it is present within a short duration and if it is going to disappear, nothing to worry.You can get a procedure called as fine needle aspiration cytology for confirmation. It helps in identifying the exact cause.The lymph node could be enlarged due to infection in surrounding area like oral cavity. Lipoma is a benign tumor of fat cells.You can ask your doctor to order this test. Take care.If you have any further queries, happy to help again.
