Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that pain and lump in the anus that leaks pus and is severely painful can be a
Perianal abscess in case if it is outside the anal opening..
It can also be an infected
anal fistula..
Perianal abscess occurs most commonly due to hairfollicle infection while other causes can be infected gland in the area or infection in the skin leading to pus formation under the skin..
While anal fistula is formed after drainage of an abscess and if it get s re infected there can be discharge of pus along with pain..
I would suggest you to
consult a Proctologist or Anorectal surgeon or you can even see a
general surgeon and get evaluated.
He can advise you a course of antibiotics, anti inflammatory painkiller and topical application of antibiotic, steroid and numbing ointment..
If it is an abscess and does not improve or start worsening then
Incision and Drainage can help in faster resolution..
In case of fistula, Fistulectomy that is surgical procedure to unroof and close the fistula is advised..
Hope this information helps..
Thanks and regards.
