What is happening to my dad?
he felt fine this morning and he told me when he got out of bed he was all sweaty but he wasn't hot. then he almost had a heart attack this morning and went back to his room to rest. then later we went to go work out and he was fine. then we went to Starbucks and he started shaking like it was so weird our whole table was shaking because he was shaking and he said he couldn't control it. he doesn't have a headache, he's not really dizzy or tired. so what's wrong?
