Hi! I had gone through your query and understand your concern. You have an bacterial infection of your sinus which I suppose It gives you a lot of troubles. Your doctor has prescribed you the right treatment an antibiotic to fight the infection and a steroid antiinflammatory to help reducing the inflammation in your sinus. I strongly suggest you to continue the treatment as your doctor has advised.I can understand that sometimes reading the probably side effects of a drug can be really frightening but you need to understand that this side effect occur rarely,not in all patient and the benefit of the treatment is incomparable comparing to probably side effects. If you don t take the treatment your sinus infection will aggravate leading to further complication. You have to trust your doc and take the treatment. Wish you good health. Dr.Rovena
