Introduction

If symptoms are atypical—such as anal itching or mild pain only, without obvious rectal bleeding; or if there is significant bleeding with blood mixed in the stool, accompanied by mucus, abdominal pain, or other symptoms; or if the location and duration of pain differ from typical anal fissures—it becomes difficult to distinguish anal fissures on one's own from hemorrhoids, perianal abscesses, or other intestinal disorders. Relying solely on self-assessment may lead to misdiagnosis and delay appropriate treatment.

Generally, if severe pain occurs during bowel movements, followed by persistent pain and a small amount of fresh blood on the surface of the stool, anal fissure may be initially suspected. However, if symptoms are atypical or accompanied by other abnormalities, it is difficult to accurately self-diagnose. In such cases, medical consultation is recommended. The details are as follows:

If symptoms match the typical presentation of an anal fissure—such as sharp, knife-like, or burning pain during defecation, temporary relief after bowel movement followed by recurrent pain lasting from several minutes to hours due to sphincter muscle spasm—along with minimal bright red blood on the stool surface or toilet paper (without mucus or pus), and recent history of constipation or straining during bowel movements, the likelihood of anal fissure increases.

If symptoms are atypical—for example, only mild anal itching or slight discomfort without obvious bleeding; or if there is heavy bleeding mixed within the stool, accompanied by mucus, abdominal pain, or other signs; or if the location or duration of pain does not align with typical anal fissure patterns—it becomes difficult to distinguish anal fissure from hemorrhoids, perianal abscesses, or other intestinal conditions without professional evaluation. Self-diagnosis in these situations may lead to misinterpretation and delay appropriate treatment.

After experiencing symptoms suggestive of an anal fissure, if they appear typical, initial management may include dietary adjustments and measures to maintain regular, soft bowel movements while monitoring symptom changes. However, if symptoms are atypical or do not improve with observation, timely medical evaluation is necessary.

Can constipation and anal fissures heal on their own?

In general, whether constipation-related anal fissures can heal spontaneously mainly depends on the type and severity of the fissure. After developing an anal fissure, it is important to first determine its type rather than blindly waiting for self-healing. In daily life, avoid prolonged sitting to reduce pressure around the anus; avoid prolonged squatting during bowel movements and keep bowel movements brief. If the anal fissure persists for more than two weeks without healing, or if symptoms such as increased pain or heavier bleeding occur, prompt medical attention is necessary.

Can patients with anal fissures run?

In general, whether patients with anal fissures can run depends on the severity of their condition and overall physical health. If there is obvious discomfort or worsening symptoms, prompt medical attention is recommended. Before running, individuals should assess their symptoms to determine the current stage of the condition. Wear loose, breathable clothing to minimize friction around the anus, and clean the anal area promptly after running to keep the area dry.
