With these "symptoms" can you say what it is? probably just leftovers from an anxiety attack...?

Yesturday on a plane i had a little anxiety attack... yannow freaking out antsy tight chest and nausea. the next flight i was fine but my chest got a little tight. when i got home randomly my back hurt a lot when i tried to breathe. this lasted for a while. a few numb spots on small random parts of my body as well. that went away when i fell asleep. i soon woke up and found that it hurt intensely to breathe in my chest and upper back and neck. now there is a little pain left and it hurts to swallow. a little tightness when i breathe too. is it possibly dehydration? oh and on and off my chest felt weird like there was a lil pressure
