Few days ago at the very end of work I used the bathroom and felt a pain. It felt exactly how it felt when I passed a kidney stone. That time I had really bad pain before it passed and went to the E.R. Well that was a expensive visit after Ultrasound and just being told to drink water until it passed. 

I feel like I passed a kidney stone withiut even knowing besides the discomfort I had. And now I got the pain in my lower back / groin afterwards. The pain is barely there now....but my stomach feels upset and making noises....and I have that heartburn feeling where my inhale and exhale feels colder than normal and my chest feels heavy.

Another thing I don't drink much....but last night had 2 margitas for Cinco De Mayo. Maybe that's giving the heartburn feeling.
