Hi, I ended up at A and E last night after excruciating stomach pain and vomiting for hours. I do have diagnosed gallstones but they haven't caused me any issues for ages so I didn't think this was the issue. I was uncontrollably shaking and felt terrible, passed out while they were trying to put the cannula in. Had blood tests and was examined and told I likely have a gallbladder infection. Got sent home.worh pain killers and antibiotics. I feel much better today lain wise but feel a bit rough so do I have an infection or not?? I'm so worried as I've never before passed out in my life, it was a horrendous feeling, I suddenly felt absolutely boiling and dizzy and it was so scary! I'm assuming they drew this conclusion from the blood tests they did? The nurse said I was probably dehydrated badly as I'd been being sick and there was just bile and water coming up at that time. Anyone else had a similar scenario? Obviously I'm going to do as I am told and take the antibiotics.
