Plague, bubonic
The most common form of the plague named for the characteristic buboes which are enlarged lymph nodes ("swollen glands") in the groin that are tender and painful. Lymph nodes may be similarly affected in the armpits (axillae), neck and elsewhere. Other features of the bubonic plague include headache, fever, chills, and weakness. The odd word "bubo" comes from the Greek "boubon" meaning groin or swollen groin.
