Black stools, xanax, extended ibuprofen use, as, chills and sweats, fainting feeling, no fever, nausea, anything match all of these symptoms?

ER-now: You may have gastric ( stomach) bleeding form extended use of ibuprofen: the black stools are ominous. Your weakness may be from blood loss. Go to ER or have someone transport you there NOW!

NOT good if melena: Dark-colored stools may result from iron supplements, foods you eat (like a lot of spinach), substances (like peptobismol), but most significantly suggests bleeding. When blood is denatured by acid in your stomach, as from ulcers, stools will turn tarry ("melena"). Blood may also be ingested from nose bleeds, bleeding gums. Stop ibuprofen (can cause bleeding ulcers) & call doctor now 4 evaluation.
