Since childhood, as I remember, I scratch a lot at my anal area to avoid itching. I have seen dermatology and surgery department and they ruled out any kind of fungal infection and hemorrhoid respectively. I consumed Albendozole tablets (anti-worm) many times and after few weeks, itching at anal area recurred. It troubles night hours and I wake up mid-night and after that I spend sleepless night. Recently, I have seen a medicine doctor he prescribed Nizonide-O (anti-worm) for 5 days two tablets daily. Two spells I consumed tablets and after few weeks the itching has recurred. Please help me to identify my cause of itching at anal area.
