I Fell On My Wrist Last Week And It Really

I fell on my wrist last week and it really hurt I thought it was a sprain and it slowly got better, two days I did a hand stand and it stated to hurt even more than it did before, now there is a huge lump on my arm and it hurts to touch the area the wrist to the half way mark to elbow, could it be fractured? Should I go to the docter?
