Cipro and dr appointment

After going to the ER for abdominal pain, I was given a CT scan and told
I have Diverticulitis, my colon was inflamed and I had an infection.
They gave me Ciprofloxcin 500mg twice a day for 5 days. My body has never tolerated drugs very well and I'm allergic to most antibiotics, but the doctor insisted if I didn't take it, I would end up in the hospital with the possibility of having surgery to remove part of my colon. So I made myself tough it out. Fortunately, I didn't get any side effects that I couldn't handle, so I did the full 5 days. Unfortunately, after two days off the Cipro, I'm feeling ill. I'm nauseas, after eating or drinking, lightheaded and out of breadth, when I stand up, and have a burning sensation after urinating that lingers till I want to scream. My muscles ache and I feel depressed. I am a 58 year old woman, very active and I don't do well with being ill. I have another Dr. appointment later today to see if I may still have an infection.
I WILL NOT TAKE ANYMORE CIPRO!
