Take a couple of Tylenol, lj. That may be about the only thing it is good for but it is good for mild fevers (and children's unexplained fevers.) If that doesn't break the fever you may have something serious and see a Dr or urgent care center. If sepsis develops it may be too late.
Just getting back to you - fever was transitory; even when very sick I rarely run a fever. Evidence of low immune system actually. I”m crawling out of it...
