Why is Emgality so painful?

I've been prescribed Emgality for my migraines, but I've noticed that the injections are quite painful. Could you explain why this might be the case? Are there any steps I can take to reduce the discomfort during the injection process? I've heard that some people experience minimal pain, so I'm wondering if there's something specific about my body or the way the injection is administered that's causing the pain. I'd appreciate any insight you can provide on this matter.
