I Think I Have A Possible Scraphoid Fracture, I Fell

I think I have a possible scraphoid fracture, I fell on my wrist about a year ago and I think I done something to it then and about 7 days ago I directly loop swung at a rock hard surface and immediately there was a purple bruise around my wrist area and it really hurt, I went to hospital and they said it was just a sprain so I left it for 7 days however it's still swollen and now I have a new burning sensation around where my carpel bones are in my wrist. However I have a high pain tolerance so I'm starting to think something could be wrong and I'm just looking for some sort of diagnosise since when I go to the hospital alone without my parent they don't take me seriously and just send me away in a splint
