I was almost 57 when I took Cipro for 3 days and woke up reeling with vertigo & balance gone. Stayed that way for 2 weeks before my brain started to adjust. Then Urologist gave me 2 Floxin and that made my head quiver inside like Jell-O, vision was like a runaway camcorder and both shoulders had tendonitis. No natural hormones, but taking Prempro. No rash that I noticed.
