New diagnosis and inhalers help!

Hi everyone,

I need some advice please as I am quite new to this! I'm waiting to see an asthma nurse in 3 weeks which feels like a long wait! I have been started on a ventolin salbutamol inhaler temporarily till my appointment. I get constant breathlessness worse on exertion. My peakflow should be 470 and often drops to 350. After 2 puffs of the inhaler it rapidly increased to 500 but still feel an underlying breathlessness and peakflow drops again after a couple of hours. Anyone experienced this? Should I be on a preventer inhaler or just suffer through to my appointment?

Any advice or tips would be great!
