I have experienced an allergic reaction to Levofloxacin: face swelled up, strong heart arythmia, throat was closing and about 24 hrs later my skin burnt leaving a dark necrotyzed patch that fortunately turned normal after a couple of days. After more than 1 year my body seems to react to any kind of medicine that i used to bare, even if taken in small quantaties. I suffer of liver pain if i eat food containing a bit of fat, regular stomach pains and now suffer of arythmia. I have a child and am scared that i couldt pass on any kind of consequence on a second one.
