Are there lymph nodes on the clavicular head of the sternocleidomastoid muscle on the lower part of the neck that is superficial but is 1.5 inches above collarbone?

Unclear question: There are supraclavicular lymph nodes. Normal lymph nodes are not palpable. If you can feel a mass or masses in the neck, you should consult a doctor. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
