[Male typing] What to you do when the doctor gives advice that you become convinced is wrong?

I have very occasional asthma attacks - less than one severe attack every couple of years, but some breathlessness maybe every couple of months.

My doctor put me on a different inhaler and within a week I developed chest pains. I went back and reported this. The doctor checked his books and that was not a recognised side effect, so off I went for a four day spell in hospital with suspected heart problems - quickly discounted - then a suspected blood clot in the lung, which was eventually either discounted or thought to be so small that it had now dispersed.

While in hospital I didn't use the inhaler and all was well. As I had suspected the inhaler all along, I didn't use it until I next went to see the doctor after for a checkup after the hospital. He told me off for not using the spray, so I started it again ... and about a week later the chest pains started to occur again. I stopped the spray without going to the hospital and the pains disappeared again.

Now, what do we make of that? I am convinced that that specific inhaler does not agree with me for whatever reason. My doctor was certainly doing his job - checking and double checking for known side effects, sending me to hospital and so on - but in the end his view was that the research should be relied on more than the symptoms I was experiencng.

(Changing doctors, by the way, is not really an option because apart from this one incident I've had 25+ years of good experience for myself and the rest of the family.)
