I've been on Levaquin for three days to clear up severe congestion, possible bronchitis. The doctor at the walk-in clinic didn't like what he heard in my lungs, so prescribed this drug (It was a Friday and I needed something before the weekend due to my asthma). My fever has continued to spike, I have cried at the drop of the hat--exhaustion, fatigue, mood swings, and a cough that persists even after three days. Pain in shoulder joint, raw throat (certain foods seem to burn it), and a REALLY bad headache, and stiffness in my neck. I go to my general doctor tomorrow (Monday), and he will hear about this medicine, trust me. It has been a weekend from hell!
