Is fever between (99-100 f )is due to endocarditis?

Unlikely as: Endocarditis is very rare...Would look at much more common causes unless you've had endocarditis before.

Not necessarily: Seems to be a bit of an obsession about endocarditis. Lots of reaons for a fever. If it persists, get it checked.

Repeat question. L: A temperature of less than 100 degrees usually is not significant. If you feel i'll get checked out by your md. Please stop asking the same question 5 times with slightly different wording. This wastes everyone's time.
