@dhofert good to hear, although I am confused about 'the surgery' you spoke of. That would be following an ortho consult in most cases. Being told you have 'arthitis' without the specifics of -impingement, anterior instability, labrum pain ect, is a pretty generic assessment and pretty common with family Docs.
From a skier/clinician perspective think of the joint this way -4 muscles make up the cuff holding the humeral head in the socket, your delts, pecs, lats and others move the humorous bone. If you have joint pain I would take a look at video of myself skiing to see if my arms stay close to my vest through out the entire pass. If so I don't have to explain where the load is coming from, if not your shoulder joints (back, and elbows too) are likely taking the load and the cause of the pain.
Just my 2 cents
