[|Human|] My husband has been shoveling rock this past week and now has a knot on his chest -  around the clavical area.  He says that it is not painful.  His father had lymphoma and he is now concerned this is what the lump is.  I feel more of a pulled muscle - no swelling under the arm pit.
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. You may have enlarged lymph node. It can be due to reactive hyperplasia, tuberculosis, lymphoma or metastatic carcinoma. Or It may be soft tissue tumor or pulled muscle. You should go for examination. Then if needed you should go for fine needle aspiration cytology or biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly. Hope I have answered your question, if you have any doubts then contact me at bit.ly/ Chat Doctor. Thanks for using Chat Doctor. Wish you a very good health.
