[|Human|] I ve had an irritating cough for a couple of weeks that comes and goes. I seem to notice the symptoms more so on my right side from my throat to my lung. I m not coughing up any phlem but today I have noticed a metallic taste in my mouth. I was previously diagnosed with bronchitis and mild asthma and have allergies to dust and dust mites. I have had chest xrays and an MRI of my chest in the past 6 months that showed nothing of concern. Any thoughts on what could be going on, and is it normal to have a problem in one lung and not the other without it being cancer?
[|AI|]  Thanks for your question on Chat Doctor. In my opinion you are having viral upper respiratory tract infection (URI) and due to this worsening of underlying bronchitis and asthma. Viral infection is known risk factor for worsening of underlying asthma/bronchitis. So better to consult pulmonologist and get done PFT (pulmonary function test). PFT is needed to diagnose asthma and bronchitis. It also tells about severity. And treatment is depending on severity only. So you may require inhaled bronchodilators and antihistamines. So your coughing is mostly due to uncontrolled asthma/bronchitis. Better to consult pulmonologist and start treatment accordingly.
