There are many causes of anal lumps with pain, as follows: First, it is possible that the stool is retained for a long time and the lower rectum drains the water from the stool to form a fecal stone. If the stone is embedded in the lower part of the anus, it can cause pain and should be crushed by hand in time to assist in enema treatment. If the fecal stone is hard and cannot be crushed, surgery should be performed in time, and the fecal stone can be removed by dilation under lumbar anesthesia. Secondly, there may be perianal abscess, such as an infection of the anal gland, which spreads along the rectum of the anal canal and forms an abscess, resulting in fever, redness, swelling, heat and pain around the anus. If there is a perianal abscess, surgical treatment should be performed in time, such as abscess incision and drainage. Thirdly, if a swelling is visible around the anus, it may be a malignant tumor, and a pathological biopsy is needed to make a clear diagnosis.
