I have a perianal abscess since 3 weeks. It's a small abscess about 5mm in size . I took antibiotics for 10days  as suggested by doctor and the pus came out. Still small firm tissue seems to be inside when touched like inflammation. Is this normal and will this go away. It is reducing everyday but process is quite slow so worried that it will turn into fistula. Any suggestions. Should I consult a surgeon.
