Extraordinare symptoms and conditions

I was prescribed Levaquin for a prostate infection. 500mg per day for 30 days. Took it for a couple of weeks and it worked, cleared up the infection, but oh my goodness, what horrible side effects...

Parathesia, especially in hands
Unpleasant dreams and fitful sleep
Heavy, heavy fatigue and weakness
Muscle and tendon pain extraordinare - twitchy too
Joint pain, back pain, you name it, it hurt
Lower left leg even feels sunburned when lightly touched
Slightly psycho / depressed

I will never, ever take this medicine again. I stopped taking the medicine over a month ago (at my physician's suggestion) but the symptoms still linger. Although, they have improved somewhat. It's nasty stuff. How on earth did the FDA approve it?
