Miserable days symptoms and conditions

I was prescribed Avelox 400 mg last week for a sore throat. I took one table per day for 5 days but those 5 days were the most miserable days of my life. I had panic attacks, short ot breath, rapid heartbeats, confusion, dizziness, lack of appetite. Last Friday and Saturday were the worse days. I went to see another doctor this past Monday and he told me that I had been given the wrong medication that could have killed med because of the side effects of the quinolones. I took the last pill last Saturday night and I still feel the side effects and don't know for how long they will last.
