Levaquin
"My doctor prescribed me Levaquin, 750 mg for 7 days) after amoxycylin didn't do the trick. I had the sinus infection for almost a month at this point, and was willing to try anything. I took the Levaquin with prednisone the first night, and had an intense anxious reaction to the combo - my pharmacy recommended I stop the prednisone, so I did. The anxious feeling subsided, and within 12 hours, I could feel my head pressure go away. However, on the second day, and until now (on the 5th day) I've slowly felt new side effects. Mainly, fatigue, achy knees and shoulders, and I wake up in the morning feelig like im burning from the inside out. I would recommend to help sinus infections,  but warning, the side effects are real. Hoping they go away!"
