As mentioned to Swebby had it checked out over the years. Not stressed just fed up with it. I am not the sort who is scared of going to the doctors. Had a lot worse than a cough to contend with over the years. Having said that I only go when needed. Have a good working relationship with my doctor. As getting appointments can be a pain she said just ring and she will ring back instead of making an appointment if it is something that can just be reasonably discussed on the phone.
Quite interesting doing my volunteering at the medical school. Last week I was a there as a patient that the student doctors had to review and assess me. Had a script about my symptoms. The script happened to indicate I had a cough. I was poked, pummelled, and tested. Some were good and others useless even allowing for their age and inexperience.
An enjoyable volunteering job. Sure beats working in the gardens at a National Trust property this time of the year.
