Ever since yesterday (2/9/2015) roughly 11am the middle of my chest started to feel really hot. I figured it was heartburn so I went ahead & grabbed 2 tums(12:30pm). However 30-45 minutes later I was noticing when taking a breath in it felt like my lungs were being stretched out. Thus it slightly hurt to breath in. . . .

After the tums I took famotidine (40mg/ 4:30pm). . . However when I'm standing I can hardly even feel the burning in the middle of my chest. But if I sit down or bend over the burning in my chest goes from 2/3 to a 8/9 for annoying.

I've never really had any issues with a burning sensation chest before. So I'm assuming its heartburn.

What did I eat/drink during the day? (Not sure if you really need it but I'll toss it in the list)

1.) small bag of cheetos (morning)
2.) slice of pasta (lunch)
3.) 2 hot dogs (supper)
3.) Sparking Water x3. (carbonated)
