am reading that there have been no law suits with levaquin due to tort reform, high legal fees, and the fact that there have not been any class action lawsuits to date. Does the black box warning give us the green light if we incurred the symptoms before it was allowed to appear in print? I don't know what hit me since this started. I wonder if others have had any diagnostic tests that give a factual background to these subjective descriptions of our pain?
