Depends on you
How old are you and what is your health history? Do you smoke? If you are over 50 and have been a smoker, you need a cxr, and if its normal someone needs to get a look inside your aiwray with a fiberoptic scope to make sure its not a polyp
or tumor in the airway.
If you aren't in a high risk category, you may not need all of this, but we can't answer your question withoutr a lot more information.
