Levaquin and oxygen level

I had been feeling like I was getting a slight head cold for several days and then on a Thursday I decided to go to an Immediate Care Facility because I felt like it was turning into Bronchitis. I am a fast healer and respond to antibiotics well as a general rule. Well, this time was an exception, I was given a prescription for Levaquin 750 mg to take one a day for 7 days. I was given a coupon for $25 off on the RX and it still cost me $130 for 7 pills. Within one hour after taking the first pill my wife and I knew I was in trouble. She rushed me to the emergency room. My oxygen level was 82, my heart rate was 140, my temperature was higher than it had been before taking the drug. Thanks to my wifes quick thinking and insistance I did not die that night. A nurse friend said she is 100% sure that if I had not been prescribed Prednisone along with the Levaquin that my reaction would have been much worse. Probably the Prednisone buffered the reaction.
I spent 3 days in the hospital. My recovery from Bronchitis was slowed down by this reaction. Then I got an eye infection and am still seeing an eye dr. for that. I have missed 2 1/2 weeks of work. Levaquin is on my list of drugs to never take again. Bob

My legs swelled immediately upon taking Levaquin with pain also in the tissues of my legs and not the joints. Breathing problems also accompanied the leg swelling. 5 months after taking Levaquin my legs are still swollen with pain and I can not take a deep breath. My oxygen level is only 94. Any advice on a cure would be greatly appreciated.
