If someone needs to blow nose during shmonah esrei, and does not have a tissue. Can the person leave his place ,and find a tissue? After which he will return to his place.
Answer:
No, it is not permitted to walk around in the middle of Shemoneh Esrei, even for the legitimate purpose of blowing one’s nose.
The Mishnah (Berachos 5:1, and poskim who follow) write that even for a serious need (a snake on one’s leg), it is not permitted to walk during Shemoneh Esrei. The Rambam (Tefillah 6:9) writes that one can only walk for purposes of danger.
Blowing one’s nose therefore doesn’t qualify.
Best wishes.
