Hi,
Thanks for writing to us.
From the description it seems you had developed a boil or
furuncle that has ruptured. Now to help the lesion resolve, just do warm water compresses over the lesion and apply
mupirocin or
fusidic acid cream. Hopefully in few days the lesions will resolve. Also please do not manipulate the lesion further as may lead to spread of infection.
Hope this helped.
Take care
