If in doubt get it checked out.
And there is doubt, so go get it checked bud.
Just though i'd "second" that,
I came off, the next night after i got out the bath i was in agoney with my left wrist. 30 mins later it was fine, But i was worried. Went to get it checked out, turned out i had broken it.
So yeah,
as terminator said, if in doubt get it checked out, and i think the fact you had a dead arm for several days is something to "Doubt"
Worth getting checked out anyway mate, even now it has gone. Better to be safe than sorry.
