I suffered a severe chest infection in early September. Amoxicillin failed so my doctor prescribed a 5 day course of Clarithromycin, 2x250mg per day. This first course made an improvement but I was still coughing week later so a second, 7 day course, 2x500mg per day, was prescribed. I suffered some side effects but this did the trick and, after 3 months, I am now much better. However, I have been left with a hoarse throat, not sore but it affects my speaking voice.
Is this common? And, if so, how long might it last? Is there any further treatment I need?
