HI,
I would agree with the above.
I wouldn't friction the calcification but iwould be asking "why is the calcification there?"
HBB no doubt is aggravating the ssp tendon, not likely the subscap tendon.
Forget the GH joint mobes, they won't do much.
Check her serratus anterior status, her upper traps ability vs lev scap overactivity.
I had a patient with bad clacification - it just sat in there and pinched everything that was in the way. Personally i think my patient needs to have it cleared because anything above the head is physically impinged - and i can't do anything about that - it is chronically swollen and sore and a structural limitation - what is your patient's calcification like?
