I've got a small lump just above my right collarbone. it's been there for almost half a year now - at first i thought it was a pimple and tried squeezing it and some pus came out. but now it's really beginning to worry me (especially after i read some of the posts here related to lumps and lymphoma).
Lymph nodes do not have pus. It sounds like a fatty cyst. In any case, go and have it checked, but it sounds strictly local.it must be on the skin if you could squeeze it. Lymph nodes in that area are well under the skin. Good luck, Sera
