I had an mri scan done which showed problems with my discs crumbling in my neck and this was one of the symptoms I had,my elbow absolutely killed,it varies between my shoulder,rotator cuff, and my elbow right down to my ring finger.as I said my oesreopath put a couple of needles,dry needling it's called,into my neck/ shoulder area and I got instant relief but it doesn't last long also it completely disappears sometimes so it could be a pinched nerve,maybe it's the same for you if your pinning your shoulders up against your ears like many of us do it could be that trapping a nerve so try relaxing your neck/shoulders more,once your aware you actually do this you tend to naturally stop and drop your shoulders more.good luck xx
