Input: These did not work at all. I had a bone infection in my leg that left bone damage and my leg will often hurt ... an aleve always does the trick but I decided to buy this bulk pack of Tylenol. The first night I received them my leg hurt and I took 2-3 pills every time I woke up in pain ... I must have taken 15 pills that night over the course of 12 hours and THERE WAS ZERO RELIEF. None at all.
Output:
negative
