Levaquin and paracetamol

I am 67 years old and I had a PSA level of 5.7 as of April 16th 2008. In the year 2000 my PSA level was 11 and Dr did biopsy and found no issues. On May 8th my present Dr prescribed Levaquin 500 Mg to treat my PSA. As of today I have taken 18 tablets of Levaquin 500 mg. On May 24th evening I started getting fever tiredness and diarrhea. Took Paracetamol 500 mg to reduce fever. Temperature reduced to 97. If I didn't take any fever reducing medicine my body temperature started increasing. on May 26th temperature started increasing and it reached 102.6 and got admitted into emergency. At emergency they did run several tests and later discharged asking me to continue with fever reducing medicine. Also I was told to continue with Levaquin 500mg. Though I am taking fever reducing medicine with Levaquin, today my body temperature reached 105. On May 19th,2008 I had a blood test and came to know that my PSA had reached 6.2. I don't want to take Levaquin any more.
