The location of the lymph nodes is important.
Lymph nodes can be swollen in just one area of the body, such as in one groin or in one armpit. Or they may be swollen in multiple areas, such as the neck and the groin, or the armpit and the groin. They can also be swollen on only side, such as one armpit or one side of the groin, or on both sides, such as both the right and left groin.
Let's start with the groin.
Do you feel any lymph node swelling in the groin, either on one side or both sides?
