Breast lumps........? - breast lumps more condition_symptoms

Hello, some time ago, I had knots in my chest and feels more and more, but I do not know if they are lymph nodes? How do I know? I will not go to the doctor because I do not think that is something, but I like 4 or 5 of them? What do I do if the lymph nodes?
I Sent a question about my previous nausea and fatigue, sometimes abdominal pain. The doctors have found anything yet? Comments?
