What is sharp pain in the collarbone area between neck and shoulder on right side?

MANY possibilities: Numerous possibilities: In that region are found bones, muscles, ligaments, tendons, lymph nodes, apex of lung, nerves, and I probably forgot some! If you have a lump there, see a doctor promptly. If pain persists, see doctor to tell him/her where it hurts, when, how often, etc. Without these details and a physical exam, we can only speculate.
