Hi Mr Connie.. If I were your treating doctor I would require much more information regarding the bump you have on your shoulder blade... You could have share with us the reports if MRI taken to help you move precisely... I would also like to know the pain details as in which site on shoulder....how is that came up initially..how bad is it..is there any movements limited..was there anything that increases or decreases your pain.. The bump can be a trigger point or a shortened muscle point... that can cause pain on pressing it..because of the shortening of the mucle and constant irritation there is always associated spasm which could be responsible for your neck pain... MRI images gives a enlarged and detailed study of screened joint or muscle..so it is very unlikely to miss out key information..as it basically magnifies and displays the image.. Don t worry.... I recommend you to keep icing your shoulder frequently to get your spasm and pain under control.. Hope this is helpful for you.. Kindly revert back incase you need any further clarification...
