urinary tract infection
"I will never take Cipro again.  After the 3rd pill, I developed tingling in my hands, legs, and feet. I stopped taking it, but the symptoms still persist.  I cannot sleep at night and the tingling is constant.  I've read this is called being "floxied" and is more common than you might think.  I am seeing a Naturopathic doctor next week to try to reverse these awful side effects.  Don't take Cipro!"
