Mahsa,
Periarthritis or changes in the capsule of the shoulder can get stretched after an unusual or continuous movement leading to this pain and stiffness of the joint.
Homeopathic Medicine has good remedies like Ruta, Chelidonium, Chenopodium, Calc flour etc. to relieve you of the pain and see that the mobility of the joint increases too.
