FQs are some of the most powerful antibiotics in terms of destroying healthy gut bacteria, and likely cause permanent gut flora changes after use. Some of the bacteria it destroys are oxygen sensitive, so they aren't in probiotics because they can't survive long enough to be manufactured into a pill. Muscle problems, especially muscle twitches, are very common among FQ toxicity sufferers. This is suspected nerve damage but there may be other factors. FQs are well known to cause tinnitus, with the suspected biological mechanism being nerve damage to the ear. Unfortunately, the medical community is severely lacking in treating these conditions, so there are no reliable tests for determining the underlying damage. It may be impossible to definitively know if any of these things were caused by the cipro.
