Cipro turned my daughter into an invalid. These side effects can be permanent, or they can resolve quickly. they are not rare, and may come on at any time within the first year after use of cipro. It is likely the most dangerous drug on the market. there are many web pages on the side effects of cipro and its class of drugs. Specifically see http://www.fqresearch.org/ and http://www.fluoroquinolones.org/
