After being diagnosed with a urinary tract infection, I was given Cipro at the hospital. My heart started racing to the point that it was hard to breath. After a while, this symptom went away. Three days later, after continuing to take Cipro, I started to feel tingling sensations all over my body, and a fiery burning sensation on my right lower back. I also had patches of numb areas all over, and suffered from muscular spasms. I developed horrible agitation episodes and tachycardia. I had rushing thoughts going through my mind and felt like running away. At some point, I felt as if I was about to have a convulsion. The doctors deny that these are side effects of Cipro and think I am suffering from anxiety. I have had anxiety before, but who hasn't? It is too much of a coincidence to have all these symptoms together right while taking Cipro.
