When a person has hay fever (allergy to pollen) does the pollen transfer from the stamen to the nose?

SneezeAnd then when the person sneezes, can the pollen travel to pistil and pollinate the flower?

An interesting question. Given  that an allergic reaction is caused by the transfer of pollen to the nasal cavity, the reverse path is theoretically possible when a person sneezes. However  the chance that  the  amount of pollen transferred is significant enough  to cause pollination is minimal.
