Probiotic drink symptoms and conditions

Following my last post about levaquin. I bought the probiotic drink ''kefir'' I noticed an instant change. After drinking a whole bottle in a days course I noticed that most of the pain went away. The burning and itching went away for good ! I could not believe it. I have began new symptoms though, I started getting light headed and having panic attacks. I am only 2 more days away from completing my 10th day off of the medicine. I am looking forward to feeling normal again. I'm getting fatigued easily and at night my feet,ankles and hands hurt but not as bad as it did before the probiotic. I hope this helps.
