Stomach Issues, IBS or Anxiety?

For the past 4 weeks, I have had a stomach pain, more uncomfortable than pain really, in the sides of my Stomach. Some bloating, and some twinges, twitches, as well as gurgling, and noises which I don't usually have. I don't know if this is stress related, nerves, or something else. I have visited my GP on numerous occasions and he has checked me over and given me Peppermint oil to settle the stomach, which hasn't really helped. I was also given Lanzoprasole, again which didn't do much. My GP thinks it could be stress related, as I have been through quite a bit over the past couple of years, and he also had some blood tests done, for Celiac Disease, and blood counts. All came back negative which is good. I have had no Diarrhea, no loss of appetite, no bleeding, no sickness or vomiting, just stomach cramps, and occasional feeling of needing the toilet. I also tried Wind-Eze, Senokot, and IBS tablets all of which did a little, but it came back. It has now subsided a little, and for the last couple of days, had pain in my testicles. I have never suffered from IBS or anything before (I am 46) or I am thinking it maybe a sudden Food Intolerance, but I have been told that most of the Intolerance Tests online are poor and awaste of money? and the NHS doesn't carry out anything like this. Could this be trapped wind? as I hear it can make its way anywhere on the body and cause pain.

IBS and anxiety go together; you may have IBS if everything else is clear.IBS tablets tend to reduce the pain but don’t always get rid of it entirely. If you are taking an antispasmodic, try a conventional painkiller on top which works better than antispasmodics alone This helped me more. BS tends to clear for a time but can come back in response to food triggers or stress. It can also be daily and constant. Mine was daily and constant because I i had no diagnosis for three and a half months and I was worried sick. After diagnosis, my IBS became come and go symptoms and I haven’t had a flare up in two years. I got IBS at age 42 following a six month bout of non stop stress. Try a food diary/low FODMAP Diet. Trapped wind goes along with IBS.
