Avelox and drs office

I,m self employed, was on a deadline job, and couldn't miss work, when i came down with an upper respiratory infection. When I couldn't sleep (It hurt to swallow and breathing deeply hurt my upper chest), I decided to self medicate with an old amoxicillin script I found in the medicine cabinet. After two days the symptoms were gone and I continued to finish the script (two 875 mg a day for 6 days). On Oct 29, I seemed to have symptoms returning so I went to my PCP. He told me not to self medicate again and said he would have to put me on a stronger antibiotic - Avelox. I took my first of 10 doses that same day at 2pm. I had no noticeable reaction until I took the second dose the next day. It was about 4 hours later, and I was standing at the counter at Lowes when I started to feel sick. I was feeling dizzy and anxious and like I was going to faint. someone got me a stool to sit on and a bottle of water. Within a few minutes I had the urge to go outside for fresh air. That helped but as I returned inside the experience repeated. I finally told the man waiting on me that I'd better continue the transaction at a later time. The next thing I remember is being picked up off the floor and asking me if I was all right. At my insistence he helped me back out the door into the cold air. I refused an ambulance and after 10 minutes of rejuvenation in that fresh air I managed to drive the half mile home. A few hours after calling the doctors office they got back to me and said it was doubtful avelox caused it. I've been taking dose 3,4,and5 in the morning and every time I experience the same symptoms. Within a half hour of taking the drug I start to feel nauseated, start burping, am shakey and I start trembling. If I try to walk my legs are very weak and shaky. I experience feelings of anxiety, am somewhat disoriented and confused. I get tingling down my arms, I tremble and feel either hot or cold. I haven't fainted any more, but I often feel like I might. I'm halfway through my 10 day regimen and will have to consider quitting, after seeing all the similar reports on this website. I'll be discussing it with my doctor on Monday.
