Omg I've had that same pain before!!!! Sometimes just moving hurt (like leaning over to pick something up or twisting around to see something behind me and getting into bed and stuff). Breathing was also hard. It hurt when I tried to take deep breaths, and I've had a coughing problem for many years, so every time I coughed, it really hurt. It really did feel like stabbing, sharp pain.

I tried to talk to my doctor, but she said it's normal?! I told my friend and she said she's NEVER gotten anything like that before.

I never took any medication for it.
It went away by itself after a while.
Sometimes it comes back, but I haven't really had it for a couple months now.
