Took A Hard Hit From A Tree Branch While Snowmobiling

Took a hard hit from a tree branch while snowmobiling to my right forearm outside area. There is a bit of swelling and an area of sharp pain when touched. Was able to continue riding all day and no significant pain with pushing pulling in any direction. So far only very light bruising. Would have just dismissed as a slight bruise but spot dime size or two with very sharp pain.
