Re: Lump in neck above collarbone. HELP!
A lump can be caused by many benign things: lymph node, swollen gland, lipoma, inflamed fatty tissue, scar tissue. Then there are the more serious causes: HIV, cancer, etc. Most lumps aren't dangerous, but it's very important to go to a doctor and have it tested just in case. If it's moveable, beneath the skin and not in a location where nodes are, my guess is it's a lipoma. But see a doctor!
