At the race two Sundays ago, I came down with a wicked fever and sinus infection. I had antibiotics leftover from a wisdom tooth infection which cleared the infection up and the fever went away on its own, but I am developing a wicked cough and shortness of breath again, just like the last time I ended up in the ER. If this Mucinex doesn't take care of it on its own, I'm headed to the CVS minute clinic and telling them to just give me the prednisone now and save me the aggravation, since that's what it took to get me better the past two times it's happened.
