Shoulder pain in middle age females can be because of various reasons like impingement syndrome, adhesive capsulitis, Rotator cuff Tendinopathy. It's good idea to visit shoulder specialist orthopedic surgeon for clinical evaluation. You may mostly need some exercises as advised by shoulder specialist who will instruct his physiotherapist to teach specific exercises. In my practice, I usually avoid electrical modalities which may be just for temporary pain relief without actual benefits on underlying pathology.
