<s>[INST] hello, i am a 32 year old female and i am 5 5 tall. for almost 2 years i have had an electrical shock like pain at the edge of my left shoulder blade. i believe that it is a muscle spasm but i am not sure. sometimes it feels knotted. i have started to also have a dull radiating pain from my left elbow which causes some numbness in my pinky and second to last finger . what could be causing these pains? i am worried that it may be nerve problems but i am not sure how i would go about getting it properly diagnosed. [/INST] HiThank you for your question.Electric shock like sensation, radiating arm pain and numbness in fingers is very typical of cervical disc problems. A herniated or bulging disc impinging on a nerve can cause these symptoms. MRI of the cervical spine is needed to diagnose the cause of nerve compression. If the MRI does not show nerve compression EMG and nerve conduction studies of left arm would be the next step.Please let me know if I can be of further assistance. </s>
