Do you have any other symptoms? You can try this respiratory illness assessment to see what might be causing your symptoms. You will still need a proper diagnosis from your doctor.
Many conditions can cause the symptoms you are describing. At the same time, you may not be sick at all.
Your best bet is to see your doctor, describe your symptoms and talk about how he or she will help you determine just what is causing the problem.
