<s>[INST] My son which is 4 and a half got a trouble with his bottom. Firstlly we thought that those are worm or something, so we have treated him for that and than repeated the treatment after 2 weeks. But he has got problems with his bottom quiete regulary evry 3 months. Evry time it does happens it last only around 3 days. If we want to book an appointment with the doctor is about 2 weeks wait for appointment and walk-in centers are only advising about tredworms. What can it be and what should we do ??
