Pneumonia
"I had been diagnosed at a local walk-in clinic with bronchitis. The next evening, however, I developed a high fever and experienced difficulty breathing. At the Emergency department, I was then diagnosed with pneumonia. This is my third day on Doxycycline and I feel so much better! Fever is normal and my lungs are not so congested and tight-feeling. The only minor side effect I&#039;ve experienced is slight nausea when taking the pills on an empty stomach. Having a  little something to eat first did the trick - though no dairy!"
