I agree. Listen to your body. Go when you really need to. Too many of us, feel we just don't have the time to go and sit in an ER for hours on end waiting on test results, only all too often to find out it was just a flu or something that your body need time to heal and work it through. We have all been on that fence, wondering should we go or should we hang in there. Fevers that persist is another good indicator that you really should be moving along to that dreaded ER. Thanks for sharing these valuable hints.
