yes, thanks Ms. 22, you did mention Eucerin cream before, I do remember that!

I'm not sure exactly what is doing it, just now making the connection that it the likely culprit is the kick-off

At one point I was trying to see if I could alternate turning left on one end of the pool, and right on the other, just to balance the muscle burden

but it was too much mental work, and it would interfere with my breathing and timing of the swimming strokes crazy

I may have to keep working on that, though!
