Hi and welcome to the forum! I am glad that I can help you.
You would like to know the cause of painful lumps around the anus.
Painful lumps around the anus may appear due to hemorrhoids, abscess (perianal or anal) fistulas, etc. Hemorrhoids appear due to excessive pushing when defecating combined with constipation. They can bleed easily. Abscess may appear due to infection of a scratch or fissure on the anus. It is painful until the pus is cleaned or discharged. Fistula is a condition when there is communication between the anus and the skin. It is a canal that usually gets infected. When there is active infection of the anus it may either develop into an abscess or a fistula. Once the fistula is formed pus and feces can be released through it. The presence of feces is a factor that causes repeated infections of the fistula.
Given the data that you described, you may or may not experience any of the conditions listed above. See an abdominal surgeon to rule out or confirm any of those conditions. You may need to have a surgery if diagnosed with an abscess or a fistula. You may need to make certain changes in your everyday life, by paying more attention to hygiene and to avoid constipation, if diagnosed with hemorrhoids.
Please keep in mind that I provide medical information only. I am not able to diagnose medical conditions online. Please contact your doctor or other qualified healthcare provider such as an abdominal surgeon for further advice and information about diagnosis and treatment options.
