Hello,
Thank you for posting your query at DoctorSpring.com
I saw the picture.
It is not an Abscess.
It looks like a Thrombosed haemorrhoid.
Please take high fiber diet, drink plenty of liquids ,eat fresh fruits and green leafy vegetables. Your stool should be soft.
If there is no response, you have to undergo surgery.
It is a simple Day case procedure.
Please consult your Surgeon and get examined clinically.
Nothing to worry.
Hope I answered your query. If you have any questions, I will clarify further.
Wish you good health.
Regards
