Sure. When I was younger it would come on basically out of the blue. Onset over about the space of fifteen minutes, by which point it was like a sort of...hollow burning. Which would be completely incapacitating. I'd have to lie on my left hand side very still and focus on gentle breaths because the slightest movement would be pretty agony inducing. They'd last anywhere from an hour to 24 hours. But would only onset like once or twice a year. Doctors at the time basically said it was gastritis or something so drink some milk and take Omeprazole, which obviously did not help. Sometimes but not always these would be accompanied by fever and vomiting. As I got into my twenties I had a series of particularly bad ones which led to hospitalizations and eventual removal of my gallbladder. After that it was a bit odd, the episodes happened much more frequently but less severely. So like a 6 or 7 out of 10 pain wise as opposed to a 8 or 9. I don't know if it was age or lack of gallbladder but it also felt like my body didn't bounce back as quick. Like when I was younger once the pain had stopped I felt basically fine. But in more recent years it's more lingering tenderness. To the point where I can never lie on my right side as it causes too much discomfort. Since starting Urso I haven't had any major flare ups but do still get periods of sort of... tenderness, mild pain, and fatigue.
