Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. You are having secretory Diarrhea as per history. You are having pain during defecation that is called tenesmus so provide the history of blood or mucus in stool if present. Get your stool routine micro examination and occult blood test. If reports show any specific parasite egg, pus cells with bacteria, then accordingly treatment needed with anthelmintic drug or antibiotic. Maintain hydration with lots of water, avoid excess spicy foods, take vital Z like powder with water or ORS frequently and consult the physician for examination. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Parth Goswami
