I had almost the same thing happen to me today, last night I went to bed with horrible pains and woke up all throughout the night, and they were still here this morning so I went to l&d but right before I left, I threw up and all the pains went away, so they said it might just be a bug, but I feel fine now
I'm feeling the exact same. I'm 16 weeks though and I was vomiting quite a bit the last couple days which is new. My entire back and down into my hips is sore. I went to the hospital all nervous and it's just tense muscles. Hopefully you'll feel better:)
I could understand if it was just in my side or one spot in my back but it was my whole back :(
You probably pulled a muscle from vomiting, sip on water and lay down to relax, if the pain won't get better call your doc
