I'm sorry to hear about the discomfort you're experiencing with anal itching and pain due to a fistula. This condition can be quite distressing.

Here are some steps you can take to manage your symptoms:

• Pain and Inflammation Relief: Medications like Aceclo Plus Tablet, which contains Aceclofenac (a pain reliever) and Paracetamol (a fever reducer), may help reduce pain and inflammation. However, this should only be taken under a doctor's prescription and guidance.

• Hygiene: Keep the anal area clean and dry. Use gentle, unscented wipes or warm water to clean after bowel movements. Avoid harsh soaps or scrubbing.

• Diet: Maintain a high-fiber diet including dals (lentils), millets, vegetables, and fruits to prevent constipation and reduce strain during bowel movements.

• Avoid Irritants: Avoid spicy foods and excessive caffeine or alcohol, which can worsen irritation.

• Medical Evaluation: Anal fistulas often require evaluation by a colorectal surgeon or a proctologist. They can assess the fistula and recommend appropriate treatment, which may include surgical intervention.

Please consult a colorectal surgeon or proctologist promptly to get a thorough evaluation and personalized treatment plan.
