Have had a non-productive cough off and on for about 2 weeks. not better or worse, and no other symptoms. not wheezing. what should i do?

Give it time: If your cough persists for more than one more week I suggest you consult a clinician for a full evaluation, physical examination, and proper assessment. Best wishes.

See doctor...: This could be a sign of bronchospasm which can be treated with bronchodilator inhalers. Some people have coughing instead of wheezing as a sign of bronchospasm. Other possibilities for your cough include post-nasal drip, GERD, bronchitis, etc. The only way to get diagnosed and treated is to see your doctor. You have been coughing long enough!!! Good luck!!!
