... the pain? if,for example eating a salad with vinegar triggers the dull pressure in my bladder, would this happen straight after eating the salad, or several hours later? Is is difficult to find which foods trigger the discomfort without knowing how soon the reaction occurs. What have you experienced and how have you found which foods are a trigger. It is confusing as some websites believe the bladder should be alkaline whereas others explain that an acidic bladder kills off bacteria. Please can anyone help, thank you
