I have to turn my SCS down when I go in a pool as well. Don't stop going in pools if you can, they are the besssst things for RSD because there is no impact. Was there any type of electricity on in the water like the pool sweeper? thats the only thing I can think of... But I do have to turn my scs down about 1/2 way when I am in a pool. But showers are fine for me
