I had very painful lower left abdomen pain that persisted long past 3 days. Went to the Emergicenter which was useless because they just sent me to the ER. After waiting for almost 2 hours and finally getting into a bed for several more hours got several bloodwork and tests that resulted to them coming to the conclusion I had an infection and had Enterocolitis. I'm home now and just dealing with pain still but I'm glad it was nothing far more serious.
