Cirrus,
I take your point.
Mine however was that doctors take/took the facile option - asthma use this ventelin (sic?) inhaler 3 times a day.
Rather than accept this easy, 10 minute appointment at the GP, ask for a second opinion at a centre of excellence. How many children of military aircrew have a diagnosis of asthma I wonder?
In 1978, or thereabout, ventilin was all the rage and
AFAIK new. Now I am susceptible to chest congestion etc and around this time caught pneumonia. The Doc, not for the pneumonia but probably for residual problems proscribed ventelin. I took a couple of puffs, neither liked it nor did it seem to do anything for me; I stopped using it.
I think he simply wanted to give it a try out. Doctors do that. They are 'encouraged' by drug companies and 'drug-lunches' to adopt their new wonder drugs.
Asking for a second opinion is your right.
