Do you see your surgeon for check ups? I see it hasn't been too long since your emergency surgery but an appointment with your surgeon or gastroenterologist might diagnose the itching inside. Not itching with every BM might simply mean the tear or itchy spot might have healed over, then the next BM might open or irritate the spot again. I avoided spicy and acidic food and sauces during my first year because it would burn and irritate. Even too much fiber or semi raw food, like a salad, would irritate coming out. Your skin and tissues will mature and toughen up, but I would still make an appointment, if the spot doesn't heal.
