pneumonia
"I was prescribed the drug Levofloaxcin  after being diagnosed with pneumonia a month ago. I was misdiagnosed twice before (for the flu, then sinus infection). I had a fever, cough and extreme fatigue. 
WORD TO THE WISE: if you have an ongoing cough, fatigue and low grade fever at night THOSE ARE TEXTBOOK SYMPTOMS OF  pneumonia. Just demand a chest X-Ray right away! 
Now onto Levofloaxcin. I took 750mgs for 7 days and it definitely did the job, I felt better in two days. The side effects *were intense* (nervousness, joint pain, increased heart rate, light headedness, insomnia). BUT it was worth it!"
