sinusitis
"After four years of chronic sinusitis with total loss of smell unless taking prednisone I was given clarithromycin. An initial 7 day course didn't quite cut it but after a further 3 days I can now smell and breathe for the first time in years!! Yes it does have some not pleasant side effects worst being nausea and leaving a horrible taste in your mouth but these are worth putting up with for the the quality of life I have now got back.. Food is once again worth eating. Let's just hope it stays this way."
