###Human: My nasal passages are swollen and I cannot breathe well. What has to be done? ###Assistant: Hi. The steroid nasal spray you are using has local steroid which helps in reducing the swelling. This spray you will have to use for around six weeks. Secondly, to treat nose block you may use local decongestant nose drops for five days. If you have excessive sneezing you should use antihistamines also. If your problem is chronic that is from a long time I would advise you to get CT scan of paranasal sinuses done to rule out sinusitis.
