I am having the same fear right now. I had taken some zithromax for bronchitis and am sure it affected my liver. My doctor says its not my liver but, I requested a liver function test and the results will be in sometime this week. He is aware of my healh anxiety.I have a issue with medicine Im afraid to take it because it may have potential side effects. I took some protonix for my stomach and am also sure it has done some damage .He has given me some xanax but I wont take it.Im driving my family nuts. Im scared and just wish I could relax. I have two children 2 and 4 I cannot let them see this.
