hands not showing after entering a negative/upper flow of water with a boat.

when I tried to swim with my boat and enter a negative water flow, it got me out of the boat and after that i couldn't hold anything in both my hands.  even if I push it away from the place it happened it wont let me enter it and move slowly when I push it. i reentered the world and the problem kept happening. I could hold items in my hands though.
