Maybe. A single groin lump could be a hernia; or it can be an enlarged lymph node, a tumor, or even an infection. More than one lump in the same inguinal area (groin) is not likely to be an inguinal hernia. One's doctor can examine this/these and determine what it/they are.
Yes. Could be hernia, swollen lymph glands, etc...Should check with your doc.
