pneumonia
"I had been on another antibiotic for 3 weeks.  When I went in for a recheck, I still had pneumonia, so was put on Levaquin for 5 days. The first day I took it in the morning & it made me light headed, so I decided to take it @ night.  It would cause me to wake up throughout the night. I would also have a burning sensation in my chest & get hot.  I went back in for a checkup & the x-ray showed that some parts had improved, but some parts were worse. I was referred to a pulmonologist.  I feel like it was too strong for my body."
