This pattern is most suggestive of a recurrent anal fissure. A hard stool can reopen the small tear, causing fresh bleeding and intense burning/pain.

Based on your symptoms, the most likely cause is an anal fissure, which is a small tear in the lining of the anal canal. It commonly develops when hard stools cause injury to the anal lining, resulting in severe burning pain during or after defecation, sometimes accompanied by slight bleeding. Since you have experienced these symptoms repeatedly over the past 4–5 months, I would suggest the following: Drink adequate water and increase dietary fibre through fruits, vegetables and whole grains. Avoid constipation and straining during defecation. A stool softener may be helpful if your stools remain hard. Take a warm sitz bath for 10–15 minutes, particularly after passing stools, to relieve pain and sphincter spasm. If an anal fissure is confirmed on examination, medications such as topical diltiazem or glyceryl trinitrate may be prescribed to promote healing. As your symptoms are recurring, I recommend an in-person examination by a general surgeon to confirm the diagnosis and exclude other causes such as hemorrhoids. If bleeding becomes heavy, you develop dizziness or severe worsening pain, seek urgent medical attention. Please let me know whether the blood is bright red and whether the pain continues for some time after passing stools. These details can help distinguish an anal fissure from other causes.
