Hello and welcome to health care magic. Thanks for your query
As per as your description it seems like you are having infection of your sweat gland
. (Hidradenitis Suppurativa
Usually the sweat glands gets blocked with the keratin and gets secondary infection with the bacterial.
In mild cases antibiotics alone will be sufficient.
In moderate to severe form steroids
injection at the site of inflammation and even some times surgical excision helps.
By taking antibiotics it will just reduce the inflammation around the gland, but does not help in removing the block, so I would suggest you to consult a doctor to access the extent and grade of inflammation and to choose the appropriate treatment option.
Wish you all the best
