10 years ago I had gallstones, I didn't know it at the time & as the pain came and went I put it down to occasional severe indigestion, figuring that as it kept going away it couldn't be anything serious so I wouldn't bother the Dr. I then started getting severe pain in my left side, right up my spine between my shoulders & in my chest every time I ate anything, even a small cup of soup. Then one day I started vomiting and couldn't stop, I ended up in an ambulance off to hospital where they discovered I had gallstones which were very badly infected and that infection had spread to my pancreas. I also had developed a stone in my bile duct. They kept me in, gave me pain killers & anti-biotics for a couple of days to bring the infection down and then took the stone out from my bile duct and a few days later had keyhole surgery to remove my stones & gall bladder. I went home 2 days later. After both ops I was eating without pain the same day and by the time I had the keyhole surgery I didn't need the pain killers either it was amazing & I was incredibly lucky. Please don't go on suffering, go back to the Dr and tell them you want something done,you're in severe pain and aren't sleeping because of it.
