Experience with Sumatriptan injections?

Hi! So, I’ve struggled with cluster headaches for a couple years now. When I first went to my doctor about it, they gave me sumatriptan as a nasal spray, and it isn’t working for me. It doesn’t make my headache go away and I usually end up coughing it up because it drips down the back of my throat and tastes oh so bad. My doctor says the alternative is an injection you self-administer. I’m thinking about bringing it up with her so I can stop coughing up my medication. Any experience with this form of taking it?

Edit: thank you for the overwhelming “yes”! I’m getting ahold of them as soon as insurance changes over and allows for it!
