supraspinatus injury

Still have sufficient ROM with slight pain while raising arm, there is a suspected acute supraspinatus strain (possibly a slight tear), no swelling or inflammation. Looking for advice in terms of increasing ROM and reducing pain without resorting to drugs or surgery and also gaining strength in this region.

hi friend
please put up a detailed information regarding this
how it happened
when
what was the problems initially and now.
is the pain present at rest
at what position pain increases
are yu experiencing any clicks in shoulder
how was it initially managed
what job you does
how the pain changes during the day
is the condition improving,remaining the same ya worsening
if pain starts how long it will take the pain to subside
is there any particular activity,movement increasing pain

It happened while doing an ill-performed handstand. There are clicking sounds (crepitus), i think indicating positive test for abrasion's sign. Neer's sign and empty can test are both positive (biased towards supraspinatus injury). pain usually worse in morning. initially injury was slight (pain present but not enough to cause problem)
