I have pain in my deltoid muscles and it comes and goes days at a time. when I went to the doctor they told me my "shoulder pain" was fascia and sent me to physical therapy but I would explain that it was my arm and going down to my elbow causing my elbow to pop very often along with pain during normal movement. my doctor and physical therapist said that counts as shoulder pain. they say it is caused by my work, data entry. is this fascia or some other type of injury
