Am I allowed to go to emergency care by myself?

I'm only 17. I live with my mom who refuses to take me to the hospital (I can't ask my dad because he lives in another state). She just says look its normal stop bothering me take medication. And that im making it up.Or whatever bull shit she speaks. It's been a week and my wrist still looks swollen. It gets numb and I feel a shooting pain. It hurts when I move or lift objects. My fingers feel "stuffy" and it hurts to close my hand. I really don't know what to do my brace that I bought is not helping at all.
I was practicing my round offs for cheer and I don't know ehat happened after I felt a major stinging pain in my wrist after doing one.
