In march 2008, about 5 months ago now, I went to Cuba. There I had a small bite of a what appeared to be a cake, but when I put it in my mouth, it tasted like wax. Stupidly I swallowed it, and that night I vomited. Since then, I have been constantly burping all day and feeling bloated. At night, it gets particularly bad when I lie down. I have had a blood test to see if there is an infection and this has come up negative. I have been prescribed ranitidine tablets which have helped but have not cured it. Does anyone know what this problem is?
