I had a horrible back pain last night that woke me up. right in the middle of my shoulder blades that would not go away. when I tried to get up my stomach began to hurt aswell. it was so swollen like I had gas. I tried to sit on the toilet to see if anything happened but it didn't and with the back pain it was unbearable. so at 2am I laid in the shower in fetal position letting hot water pour on me. odd thing was burping helped relieve some discomfort. so as I cold as I was I tried throwing up, sitting on the toilet but nothing. all I could do was cry. my stomach was so tight. I asked me baby to please move a little to know everything was ok. that the pain was just temporary and it happened. I made my way to bed, pain and all I fell asleep. thank God this morning it's like nothing ever happened..
