Levaquin and nitro tablets

Two weeks after taking Levaquin for a urinary tract infection, I developed a rash/hives that covered my entire body. I had frequent violent itching attacks and wanted to scratch my skin off. After two days of the hives, I went to Urgent Care and was given a steroid shot and Prednisone. The next day I had severe chest pains and shortness of breath. I went to the emergency room and and EKG came back abnormal. My white cell count had shot off the charts to 35.0 I was admitted to the cardiac unit and was put through a battery of heart tests. All came back unremarkable. After three days of blood tests, CT scans and nitro tablets, I was released with no conclusion as to what I was experiencing. The rash continued, just not as bad and I've experienced joint pain. One week after the intial symptoms, I began experiencing dizziness and loss of vision. It has now been two weeks. I've had a MRI on my head to determine the cause of the dizziness and the vision loss and results from the MRI are pending. I was a healthy 46 year old before taking Levaquin. Currently, I cannot work a full day without vision loss or dizziness. I've been so perplexed as have the five doctors I've seen as to what the cause of my symptoms could be. After reading many comments from Levaquin patients, I now believe that I've found the cause.
