I am a 15 year old girl and I?ve been having shoulder, collar bone, and finger pain on my left side for 3 weeks. 3 weeks ago I hurt My shoulder and I heard and pop and right after that I had this pinching pain on my collar bone and shoulder. The next day my whole left arm and fingers were hurting. I went to the doctor and they said I need a mri scan. My finger pain has gotten worst to the point were I can?t pick up heavy things. My shoulder hurts when I try putting my hair up and when I try putting it in a straight line on the side. So yeah my finger is really weak and my collar bone and shoulder still hurt. I?ve been having sharp pain for 3 weeks and my appointment for the mri is not till next week.
