What is the best remedy against shoulder pain (muscular spasm)?

[ansalia]

I have been diagnosed first with a "frozen shoulder" and then with "some unspecific injury". It is neither, I am convinced it is stress and a spasm. What is the best remedy against shoulder pain (muscular spasm)?

Well:

Who diagnosed "frozen shoulder?" and how?
What treatment were you given?
Who diagnosed the "some unspecified injury?"

even wuth a frozen shoulder , it's important to keep it moving. If you lean over forward and let your arm swing it should be less painful than movong it up and down
