I am a Flight Attendant and after work yesterday, later in evening, I noticed pain near xiphoid process. Also, I lifted a heavy box from Costco, up two flights of stairs. I didnt lift any particularly heavy luggage items, during flight, but was engaging in some pretty aggressive rearraning of pax luggage in overhead bins. Felt ok, when I got home, but suprisingly the pain increased til bedtime and was really bad during nite. Any suggestions! Claudia
