Hello~you could have a form of GERD, this can cause stomach pain and gurgling. I would take some high potency probiotic to put the friendly bacteria in your gut.
Also, believe it or not, you may have some misaligned vertebrae in the middle of your spine, they control the functions of your stomach, I suggest seeing a chiropractor for a few treatments, I know mine helps at times with my tummy issues. He/she will take some x-rays and after reading them,start treatments in the offending area. After a few visits, you should start to feel better.
