Avelox and alergic

I had broncial or sinusitis infection and always cough to release mucus. My Immunologis prescribe me 10 day avelox. After six or seven days I am having chest pain at right side close to armpit. It pain every take deep breath in chest. It also pain every time coughing. After all pills finish I still have mucus and I feel pain in my chest every time I inhale. I couldn't stand the pain when coughing. I never had alergic to medicine before and this the first medicine that I knew I had severe reaction. The last pil I take is two days ago but my pain in chest not decreasing. I also had reaction like rash, the skin in my scrotum feel very ithcy and hydrocortisone not helping much since I take avelox. This medicine should be banned.
