Avelox Sinus Infection, Chest Pains, Augmentin, Panic Attack, Tremors

I was prescribed a 10 day course of 400mg Avelox for a persistent sinus infection that failed to respond to a 9 day course of Augmentin. The first day I took it I had no side effects except for a fleeting pain in my right knee which I had injured many months before. The second day I started feeling slight pains in my other joints in my shoulders, elbows, and wrists. They were very mild so I ignored them and continued to take Avelox. The third and fourth day I started experiencing nausea which lasted approx 2 hours after taking Avelox. On the 5th day I started getting tremors 30 mins after taking Avelox, I felt like my body was coming apart from the inside. That night I felt on edge the whole night like I was about to have a panic attack at any midnight. I woke up in the middle of the night with chest pains. The next day I called my doctor and requested that he switch me to another antibiotic. Its been 4 days since I last took Avelox and I feel almost normal again except for the pain in joints all over my body which I hope will fade with time. Please think twice before you take this medication when there are so may other alternatives out there. If you do decide to take it be very careful and make sure you're not alone for the two hours after you take it. Don't be afraid to question your doctor if you have any concerns. I would never take this drug again unless I it was the last resort.
