Hi, may I answer your health queries right now ? Please type your query here..My husband had a heart attack 11 days ago and had three stents put in, one the day after the attack and two more the following day. He developed a fever and chills and had to go back into the hospital a week later. IV fluids and antibiotic seemed to help and he was released two days ago. Doctors did blood culture, urine culture, EKG, ECHO, ultrasound of gall bladder and found nothing. He isn't having any pain and the site of the procedure looks fine. Now the fever is back. Any ideas?
