diverticulitis
"Day 3 on Flagyl and Cipro. I thought I was having a heart attack. This stuff has horrid side effects. Discomfort in my chest and arm. Foggy headed feeling,  dizziness, unbalanced, headache, very nauseous,  metal taste, very blurry eyesight. 
No energy, at 55 it is not a good thing to feel this way, especially when you are overweight and out of shape. This is only day 3 I don't think I can take this stuff for 7 more days. They say the IV kind is worse though. Supposedly it's helping (I do feel less pain in my abdomen I think). IF I make it through this stuff I bet I will watch what I eat and make better choices in the future. I called the pharmacy and the doc and both said to stay on it, cipro 2X daily and flagyl 4X daily. Scary stuff."
