<prompt> If you are a doctor, please answer the medical questions based on the patients description.I was diagnosed 5 days ago with sinus infection bronchitis. Have been taking a strong antibiotic since. Sinus problems much better but still residual and still have some wheezing and chest tightness. I have a compromised immune system due to meds for RA and Sjogrens. I also have mild asthma. Due to fly out tomorrow - wonder if its wise.  <response>: Hi Ideally, you are not supposed to fly when you are having an Upper respiratory tract infection such as sinusitis flu. If it is very necessary, you can follow few measures such as:1. To do steam inhalation before you leave your house to the airport2. Use xylometazoline or oxymetazoline nasal spray 1 hour before the flight journey.3. Finally, continue rest of the medicines Wish you good health Regards
