I've been getting bouts of abdominal pain and vomiting, a few weeks apart. I've seen the doc who has given me painkillers and is organising an ultrasound as she thinks there's a possibility I might have gallstones. She says if I do need an op, the wait might be a long one. Has anyone got experience of gallstones and any advice on how to manage until the scan/diagnosis/possible op? I'm a little overweight, but not obese. Will losing more weight help?
