Hello and welcome to HealthcareMagic..
I'm sorry to hear this..
I thank you for posting your query here..
I being a surgeon, we encounter so many such cases day in and day out..
I read your question completely and have understood it well enough..
I will analyze all your points, please note..
1. Do you have pain? Suffering from Constipation?
If you have pain along with
fever then you may be having
perianal abscess.
2. If not, I strongly feel you are suffering from, fistula in ano.
This disease classically presents like the way you describe. Pus or yellow discharge and blood occasionally.
3. Please let me the details..

I am a master of such diseases and definitely can help you better.
Take care.. God bless..
