Hello, i have a mild issue in deep breathing in i.e feeling that breath doesnt go deep enough on inhalation during day time. I also sometimes get very mild cough in the morning on getting up. Doctors prescibed Pantos40mg twice a day but no relief since 3 weeks. I sleep without any problem at night. What can it be? I have no other symptoms and feel fine. only this deep breathing issue is really annoying and scary and normal breathing is fine.
