Gallbladder or Reflux?

For the past 2 weeks I have been waking up in the middle of the night in absolute pain. The pain seems to be in my stomach and radiates to the back causing me severe back pain. It happens in the middle of the night. Last night it was 4am when it started and did not calm down until after 8 or so. I am exhausted. This has happened a 2-3 times a week causing me to loose sleep and spend hours in pain with no relief. I thought since I work late and sometimes either eat late or have a snack lete, maybe it was causing my tummy to ache. But sleeping on my stomach, Tums - nothing helped. After limiting myself to not eating past 8pm, It still continued. Last night was enough. It was miserable. I toss and turn in horrific pain. After finally getting a couple hours of sleep this morning, I called the advice nurse to see what I can find out. Her concern was Gallbladder and she wanted me seen today! I was able to get in at 3:45 , which left me missing half my shift. Now, after an X-ray an blood work, hear I sit waiting. To be honest,  I have not felt myself after having Luke. I remember it took some time after Andrew until I felt good again, well over a year I'd say.

Wish me luck! I should know something tomorrow!
