Hope I have answered your query.
I will be available to answer your follow up queries.
Since you do not have any other major symptoms that i have mentioned, this is just a benign issue and most probably associated with stress.
If the pain subsides on its own without any intervention or medications, and it does not affect your day to day life, then, there is no need to be concerned at all.
Wish you Good Health.
