I just started taking hyoscyamine today for the first time. I have been living with this painful eating problem for several yrs, having colonoscopy every 5 years with no sign of disease, so I just figured it was stress. After 2 visits to the ER, I figured it was time to get a diagnosis. Have another appt tomorrow with MD as a followup to see how I have been doing. Not much has changed, but the pain is less severe.
