Hello. I have persistent fever for about 3 weeks. Each day between 36.8-37.3. I had palpitations but I was also stressed searching for possible infections. My blood results are good. I stayed in hospital for one week and they did not discoverd anything. My VSH is 3/h and 6/2h. No stafiloccocus. The EKG was good. Don’t know what to think and why this temperature persists. My abdominal ecography is good. Good results at penumology hospital as well. Could it be endocarditis infection? Thank you !!!
