Feels like someone punched me in the back and I"m out of breath.?

I've done Zumba for the first time last week. And had a migraine the next day and started to feel more out of breath. I did stop a medication on that weeks Monday for the same symptomes. ON Sunday we did a walk and I starting feeling out of breath and a pressure point in my back. Near the end of the walk the right bottom side of my face got numb a bit. Took a few hours to go back to normal. My mom said she's had that feeling when over stresses. I didn't go to bed when I came back and probably should of and will next time. I'm just wondering if this is due to over exertion, anxiety or heart related.

What do you think.
