Clarithromycin
"I have been given this medicine every year for the past 3 years when I get bronchitis. Every year, I forget about the symptoms from previous years but I am done taking this medicine. After the 3rd or 4th day, I get really bad muscle aches and the Dr's don't do anything about it. I can't sleep and will come to the point that I can barely move because of all the pain I am in. I will start remembering this from now on so I don't experience it again."
