My husband had his stent removed (from his kidney to his bladder) this past Thursday, (operation was July 12th)- and has felt more feverish over the past few days - he was sent home with two meds - penicillin (4 daily), and flomax. His temp. has spiked at least to 29.3 each day. He s bringing it down with Tylenol. Pain during urinating has almost ceased. When should the spikes in temperature stop?
