I have been coughing and sneezing after cleaning houses, dust and cats are my allergies, lately I have been noticing a tightness in my chest when I cough and a metal taste in my mouth only when I cough. This is the second time it has happened.  About three weeks ago I had a back tooth pulled as it was infected, however much better now and no pain and swelling is gone, I wouldnt think it would be that.
Hello, Thank you for asking at Chat Doctor. I went through your history and would like to make suggestions for you as follows:1. I usually prescribe my such patients levocetirizine and montelukast for 2-3 days for symptom relief.2. For patients with tightness in chest, wheezing, difficulty breathing, etc., I also add albuterol or levosalbutamol for relief of bronchoconstriction.3. If you have such symptoms only second time, no regular medication is required.4. As an Allergist-Immunologist, I would suggest you allergy testing for house dust mites, molds, insect proteins, pollen and cat proteins. This will help to identify the substances causing allergies to you and also to know the measures to avoid them.5. Based on allergy testing, an Allergist-Immunologist may prescribe you allergen specific immunotherapy, however, I suggest it only for those who have repeated/constant symptoms. Hope above suggestions will be helpful to you. Should you have any further query, please feel free to ask at Chat Doctor. Wish you the best of the health ahead. Thank you & Regards.
