A swollen and tender node in the axilla can be due to Hidradenitis suppurativa, which is a chronic inflammatory condition that affects apocrine sweat glands. It can also be due to a furuncle, which is a localized skin infection of a hair follicle. Both conditions can present with a swollen and tender node, which has increased in size over a few days. Epidermoid cysts typically present as a painless lump and are not associated with lymphadenopathy.
