Hi doctor, I am seeing slight increase increase in temperature in evening ( max 99.2). It goes normal in night ( 97.8). And remains around 98.7 throughout days. This is happening since many days around 4 weeks. There is no other symptoms apart from this. I did complete CBC test in aug 2020. All parameters were normal expect RBC count was 6.3 increase. Could there be such symptoms due to increase in RBC ?? I am bit worried. Please read question and answer.
