Woke Up With Leg Cramp. Stood Up And Massaged It.

Woke up with leg cramp. Stood up and massaged it. Realized I was having heart burn, my ears felt like they were stopping up and filling. Then my ears felt stopped up. The back of my neck and back were very very hot. I sat and drank water. Had trouble breathing. Nausea too. Then it all seemed to slowly go away. And now I'm sitting here. My left leg still hurts.
After my ears unclogged all the symptoms went away except for the leg cramp.
