I suffer with asthma, the last few hours I have a been getting a shooting pain in my left side?

I suffer with asthma, the last few hours I have a been getting a shooting pain in my left side when I breathe. I also keep catching my breath and finding it hard to breathe. I have been taking my inhaler regularly and when I feel I really need it but it hasn’t helped, do I need to visit a hospital or doctor?
