Hi, my stomach has been doing the same thing for the past 3 years! I sware when it first started, I thought I was pregnant! I even took a pregnancy test. My daughter got pregnant with my beautiful little grandbaby at the same time this started and I thought I could even be feeling her sypmtoms, kinda silly but I've heard it happen but not with grandma's! LOL!!!
Anyways, this past year my back pain has been real bad and the 2nd week of FEB, of this year I got sick with chron's and ulceritive colitis and was in the hospital for 11 days. Now I'm sick and have to learn about eveything. I would go to a doc for your symtoms and see if you are starting to have some kind of stomach problem, or maybe you pulled a nerve in your back. I don't know, it could be a number of things. But I hope it's nothing serious.
