Please help me stop driving myself demented. I had DD2 4 months ago, for last 2 months have had persistent tummy ache and heartburn, with an intermittent sensation of something being stuck in my chest (like when you don't swallow a pill properly). Been to GP several times who thought it was acid reflux and prescribed ranitidine and then omeprazole but neither seem to have much effect. Have been referred to a gastro specialist, in meantime am worrying myself stupid about early symptoms of stomach cancer. I'm 31 and know this is statistically unlikely but am terrified nonetheless...
