Please tell your doctor that you are concerned that your child is on so much medication and if there is anything you can do other than so much medicine, like a special diet, exercise, lots of fluids, humidifer at nights - just water - and let it run it course. Sinusitis doesn't go away overnight - I have had it off and on for years. I had one sinus infection after another even after having polyps removed from my sinuses. Now I am possesed with allergies - the worst you can imagine - and I refuse to go back to the doctor and get on more prescritions as so many have side effects. My doctor says when there is color to your mucuos then that means an infection. I am finding that is not true. I sneeze, cough, have itchy eyes, runny nose and even breathing problems, but every time it rains I get much better. It is a lot to deal with always blowing my nose, especially at work, and feeling and talking like I have a cold, but another thing that helps is the little bottles of saline you can get to squeeze into your nostrils. You may want a second opinion as to how to treat this.
