I Fell And Landed On My Right Hand. The Joint

I fell and landed on my right hand. The joint below my thumb. And ontop of my palm an above my wrist is swollen from wrist to thumb. If I try to hold a cup of coffee more then five seconds I'll lose it. An trying to feel or touch anything with it it tingles an try to grip an pull it hurts me. What do i need to do to get my thumb strength back? I have insurance that well pay! All i need is a specialist to check it out.
