I've undergone a month of pt per my dr. For scapular dyskinesis but my shoulder's still sore & unaligned. Why hasn't it gotten better? What's next?

Swim. If and when you are able, swimming is very good for many musculoskeletal misalignments. Muscles have memory and it takes consistent effort to change their positioning.
More PT. Mainstain of tx for diagnosis of scapular dyskinesia is therapy, with strengthening/reeducation of periscapular musculature. For longstanding symptoms ths may require months of supervised therapy as well as an independent home program. Bottom line: don't get frustrated and stick with program. If diagnosis is in doubt seek second opinion from experienced shoulder surgeon.
