I'm not sure if I should be posting this here since im pretty sure I dont have lymphoma, but I wasn't sure where else to post my question. This morning i discovered a lump im my inguinal lymphnodes. It is about a centimeter in diameter, tender, and mobile. There is no redness or any abnormal appearance on the skin over the area. I do not currently have any illnesses or infections. Is this something I should be worried about or should I just keep an eye on it?
