I have been having consistent stomach aches for the last two-three days. I have been burping uncontrollably. I have this acidic, foul odor/taste in my mouth. It is hard for me to have a bowel movement. My stomach was super bloated, so I took a natural laxative (Smooth move). I recently starting just eating fruits (juices) and vegetables (salads), but I had the gas (burping) for a while (maybe a month or so). I have also had bad breath for a while. I think it has something to do with my digestive system. But just recently, I now have the burping and pains in my stomach; along with the acidic taste in my mouth. What could this be?
