Hello cankat,

Generally speaking, painful lumps that are movable are benign. When the lump is painless and stationary, more concern should be raised. Monitor the size and note any change in this aspect as well as pain and mobility. If there is a marked change, see your local physician promptly. Lymph nodal regions can be areas of concern as they are the termini of the lymph ducts that run from all areas of the body and filter bad things (bacteria and virus) as well as metastatic cancer cells which may lodge to form lymphoma. At any rate, keep a close eye for fever, night sweats, or anything out of the ordinary.

Best-
