In reply to MarcusP:
Sub-Acromial decompression and removal of bursa for me in May 2015.
Posh tape did V. little to help pre-op and nothing post.
A foam roller and lacrosse ball deep in the lats and traps 15 minutes 2x a day worked really well, to release tight muscles pulling in odd directions.
Stabilisation exercises (banded pulls, kettle bell press etc. ) to get the muscular coordination working. Then using weights to get strength back (deadlifts, bent over row etc.)
Six months on and I am getting strong again - still mobilising on a foam roller twice a day (as little as 30 seconds.
Good luck
