 [ Symptoms ] i have a high fever101 5 and i have not been able to go to the bathroom#2 for three days what is going on [ Disease ] it is impossible to know what is going on without a physical examination a persistent fever of 101 5 in an adult is worthy of an urgent care visit especially with the constipation issue and especially if you have any other symptoms such as vomiting or pain a fever normally indicates an infection when the body ramps up production of antibodies to fight an infection it causes a fever however a fever of 101 5 for two days is not normal in an adult i would suggest you get this checked out as soon as possible wishing you all the best
