Its normal for people to feel all sorts of sensations, sometimes at the point where one feels the touch of the breath. Just keep your attention firmly focused on the point where the breath touches with a relaxed mind. If you are still having trouble discerning the touch of the breath, go back to the instructions. Either make some intentionally hard breaths to find the anchor point of your breath or stop breathing (temporarily) and observe the point where the breath normally touches the body, then breathe again normally.
The difficulty (and beauty) of anapana-sati to develop samadhi is that as one's concentration develops, the breath becomes more subtle and harder to discern, which then sharpens one's samadhi. Keep in mind also that the practice of anapana is a preparatory tool to practice vedananupassana (observation of the anicca characteristic of sensation) throughout the body.
“No lists of things to be done. The day providential to itself. The hour. There is no later. This is later. All things of grace and beauty such that one holds them to one's heart have a common provenance in pain. Their birth in grief and ashes.”
- Cormac McCarthy, The Road
Learn this from the waters:
in mountain clefts and chasms,
loud gush the streamlets,
but great rivers flow silently.
