Stitch Sinus After Breast Lift and Implant. What Should I Do About it?

next week I will be one month post op, I got absorbable stitches , and there one one place where there is a hole deep and when I touch it its like the stitch wont be absorbed and little red but it is so small and last time when I asked my doctor he said I don't have to be worried about it ! but its a deep hole directly near my areola. What should I do ? is it going to turn to an infection or maybe it will be a hole in my skin like that because its about a month now ?
