I 'm very worried as I have gut inflammation, raised calprotectin levels, my gerd has worsened, swollen stomach, nausea, fatigue, bloating and struggling to eat and a lump just under my belly and tender pain in my stomach. My acid reflux is bad as well. I'm seeing a gastrologist at Ashford One who says it's a bit of IBS. My doctor thinks it might be ovarian issues as I have endometriosis and have red patch in my mouth near bottom teeth. What tests do I need?
