Hello @oerin and welcome to Mayo Connect,

I'm pleased to hear that you are recovering so well from your surgery and able to get back to swimming. You must feel great to be back in the water again.

While we wait for others to post who have had rotator cuff surgery, have you considered any therapeutic PT in the water? My local YMCA has water therapists who will work with people in the pool to strengthen then in their recovery from disabilities and/or surgeries.
