Answer 5

nothing.stop worrying

Answer 6

It is most likely nothing to worry about; have you been exercising or overextended the muscle in some way?  Even carrying heavy shopping bags, backpack, etc. could stress the muscle.  If it would keep bothering you for over a week or two, then I would have it checked out.
