The pain ie entirely muscular in nature. If that is bony you willnot be able to move your arm.
You can use some muscle relaxant
and pain kileers such as Ibuprofen
as pain killer and muscle relaxant such as muscuril for 05 days that will relief your pain.
I hope I am sucessful in solving your query if you have more you can ask me.
