I have just come out of hospital after emergency surgery.
I had gallbladder attacks for years, and had planned to 'manage it' with a healthy diet which was going well, but two weeks ago the pain became constant and I could not keep any food down, not just fatty food but everything. I went to the drs after a wait and he sent me straight to A&E.
They decided to take it out straight away after seeing the ultrasound and looking at my blood tests.
My best advice is to go to ED if you are in severe pain. There are risks to leaving it - infection, rupture, and liver damage etc etc.
I am now at home recovering. I would say the operation was quite simple, and just a few paracetamols for a few days, and the discomfort is quite manageable. I am quite tired though, very bruised and tummy still like a football. I feel overall so much better even now, pain has gone and I feel a lot lighter and better (I am a stone lighter literally, but just all aches, pain, feeling sick and tired all of that has gone)
I was scared I had left mine for too long and had caused real damage. So I would not advise leaving it too long. Push for an ultrasound and MRI to check what is going on, blood tests for sign of infection.
