Under general anaesthetic. Anybody else find that you couldn't swallow for a day after it? They tried giving me toast tried to eat it but it wasn't happening. I had to abandon the toast, they gave me soup. I ate that fine. Had it as got more health issues which we discovered about 4 weeks ago is in fact my gallbladder. Endoscopy showed up fine which we knew it would. I hope I never have to have an endoscopy again.
